We expect a rectangular hole of size 4x3 in the resulting triangulated plane. diff --git a/data/examples/Filtering/ConstrainedDelaunay2D.py b/data/examples/Filtering/ConstrainedDelaunay2D.py deleted file mode 100755 index c165865..0000000 --- a/data/examples/Filtering/ConstrainedDelaunay2D.py +++ /dev/null @@ -1,118 +0,0 @@ -#!/usr/bin/python - -# noinspection PyUnresolvedReferences -import vtkmodules.vtkInteractionStyle -# noinspection PyUnresolvedReferences -import vtkmodules.vtkRenderingOpenGL2 -from vtkmodules.vtkCommonColor import vtkNamedColors -from vtkmodules.vtkCommonCore import ( - vtkMinimalStandardRandomSequence, - vtkPoints -) -from vtkmodules.vtkCommonDataModel import ( - vtkCellArray, - vtkPolyData, - vtkPolygon -) -from vtkmodules.vtkFiltersCore import vtkDelaunay2D -from vtkmodules.vtkRenderingCore import ( - vtkActor, - vtkPolyDataMapper, - vtkRenderWindow, - vtkRenderWindowInteractor, - vtkRenderer -) - - -def main(): - colors = vtkNamedColors() - - # Generate a 10 x 10 grid of points - points = vtkPoints() - gridSize = 10 - seed = 0 - randomSequence = vtkMinimalStandardRandomSequence() - randomSequence.Initialize(seed) - for x in range(gridSize): - for y in range(gridSize): - d1 = randomSequence.GetValue() / 2.0 - 0.25 - randomSequence.Next() - d2 = randomSequence.GetValue() / 2.0 - 0.25 - randomSequence.Next() - points.InsertNextPoint(x + d1, y + d2, 0) - - aPolyData = vtkPolyData() - aPolyData.SetPoints(points) - - # Create a cell array to store the polygon in - aCellArray = vtkCellArray() - - # Define a polygonal hole with a clockwise polygon - aPolygon = vtkPolygon() - - aPolygon.GetPointIds().InsertNextId(22) - aPolygon.GetPointIds().InsertNextId(23) - aPolygon.GetPointIds().InsertNextId(24) - aPolygon.GetPointIds().InsertNextId(25) - aPolygon.GetPointIds().InsertNextId(35) - aPolygon.GetPointIds().InsertNextId(45) - aPolygon.GetPointIds().InsertNextId(44) - aPolygon.GetPointIds().InsertNextId(43) - aPolygon.GetPointIds().InsertNextId(42) - aPolygon.GetPointIds().InsertNextId(32) - - aCellArray.InsertNextCell(aPolygon) - - # Create a polydata to store the boundary.

Note - To really appreciate the complexity of some of these surfaces, select a single surface, and use the options `-b -n`. Also try specifying wireframe (toggle "w" on the keyboard) and zooming in and out. -!!! Tip - If you color the back face, the three-dimensional orientable surfaces will only show backface coloring inside the surface e.g `ConicSpiral` or `Torus`. For three dimensional non-orientable surfaces; backface coloring is visible because of the twisting used to generate these surfaces e.g `Boy` or `Figure8Klein`. - -!!! Cite - See: [Parametric Equations for Surfaces](http://www.vtk.org/wp-content/uploads/2015/11/ParametricSurfaces.pdf), for more information. This paper provides a description of fifteen surfaces, including their parametric equations and derivatives. Also provided is an example of how to create your own surface, namely the Figure-8 Torus. diff --git a/data/examples/GeometricObjects/ParametricObjectsDemo.py b/data/examples/GeometricObjects/ParametricObjectsDemo.py deleted file mode 100755 index 43be06b..0000000 --- a/data/examples/GeometricObjects/ParametricObjectsDemo.py +++ /dev/null @@ -1,416 +0,0 @@ -#!/usr/bin/env python3 -

-An artifact called aliasing occurs when sub-sampling and is often associated with stair-stepping edges. Sampling theory proves that discrete sampled signals with spacing S, completely describe continuous functions composed of frequencies less than S/2. When a signal is sub-sampled, its capacity to hold high frequency information is reduced. However, the high frequency energy does not disappear. It wraps around the frequency spectrum appearing as a low frequency alias artifact. The solution, which eliminates this artifact, is to low-pass filter before sub-sampling. - -Low-pass smoothing reduces the high frequency range of an image that would cause aliasing. The same aliasing phenomena occurs when acquiring data. If a signal from an analog source contains high frequencies, saving the analog data in a discrete form requires sub-sampling that will introduce alias artifacts. For this reason, it is common practice to acquire data at high resolutions,then smooth and subsample to reduce the image to a manageable size. - -This example demonstrates aliasing that occurs when a high-frequency signal is sub-sampled.

-Although preprocessing can do a lot to improve segmentation results, postprocessing can also be useful. Morphological filters, which operate on binary or discrete images, can be useful for manipulating the shape of the segmented regions. In this brief discussion we will only consider operations that use circular footprints, even though these morphological filters can be defined much more generally. - -Erosion is implemented by removing pixels within a specified distance of a border. For each pixel not in the segmented region, all the neighbors in a circular region around the pixels are turned off. This erosion filter shrinks the segmented region and small isolated regions disappear. - -The opposite of erosion is dilation. This filter grows the area of segmented regions. Small holes in the segmented region are completely closed. Any pixel not in the segmented region but near the region is turned on. - -Dilation and erosion are dual filters with nearly identical implementations. Dilating the “on” pixels is equivalent to eroding “off” pixels in a binary image. Holes in the map disappear. However, dilation alone also grows the boundaries of the segmented regions. When dilation is followed by erosion in a closing operation, small holes are removed; however, the boundary of the segmented regions remain in the same general location. - -Opening is the dual of closing. Opening removes small islands of pixels. It is implemented with an initial erosion, followed by a dilation. - -Connectivity filters can also remove small regions without affecting the remaining boundaries of segmented regions. This set of filters separate the segmented pixels into equivalence classes based on a neighbor relation. Two pixels belong to the same class if they are touching. There are two common neighbor relations in two-dimensional images: four connectivity considers pixels neighbors if they are edge neighbors, and eight connectivity considers pixels neighbors if pixels share any vertex. - -This example demonstrates various binary filters that can alter the shape of -segmented regions.

-The first step is to choose dependent and independent variables. This choice is essentially a mapping from multidimensional data into an unstructured point dataset. This example chooses MONTHLY_PAYMENT, INTEREST_RATE, and LOAN_AMOUNT as (x, y, z) point coordinates, and TIME_LATE as a scalar value. This maps four of six variables. For now we will ignore the other two variables. - -The example uses vtkGaussianSplatter to perform the splatting operation (i.e., conversion from unstructured points to volume dataset). This is followed by an isosurface extraction. We splat the data two times. The first time we splat the entire population. This is to show context and appears as gray/ wireframe in the figure. The second time we splat the data and scale it by the value of TIME_LATE . As a result, only payments that are late contribute to the second isosurface. The results of this visualization are interesting. First, we see that there is a strong correlation between the two independent variables MONTHLY_PAYMENT and LOAN_AMOUNT . (This is more evident when viewing the data interactively.) We see that the data falls roughly on a plane at a 45 degree angle between these two axes. With a little reflection this is evident: the monthly payment is strongly a function of loan amount (as well as interest rate and payment period). Second, we see that there is a clustering of delinquent accounts within the total population. The cluster tends to grow with larger interest rates and shrink with smaller monthly payments and loan amounts. Although the relationship with interest rate is expected, the clustering towards smaller monthly payments is not. Thus our visualization has provided a clue into the data. Further exploration may reveal the reason(s), or we may perform additional data analysis and acquisition to understand the phenomena. - -One important note about multidimensional visualization. Because we tend to combine variables in odd ways (e.g., the use of MONTHLY_PAYMENT , INTEREST_RATE , and LOAN_AMOUNT as (x, y, z) coordinates), normalization of the data is usually required. To normalize data we simply adjust data values to lie between (0,1). Otherwise our data can be badly skewed and result in poor visualizations. - -!!! info - See [Figure 9-50](../../../VTKBook/09Chapter9/#Figure%209-50) in [Chapter 9](../../../VTKBook/09Chapter9) The [VTK Textbook](../../../VTKBook/01Chapter1). diff --git a/data/examples/Modelling/Finance.py b/data/examples/Modelling/Finance.py deleted file mode 100755 index 1fe4959..0000000 --- a/data/examples/Modelling/Finance.py +++ /dev/null @@ -1,202 +0,0 @@ -#!/usr/bin/env python -

-This example shows how to align two vtkPolyData's. Typically, the two datasets are related. For example, aligning a CT head isosurface with an MRI head isosurface of the same patient. Or two steps in a time series of an evolving surface. These cases usually reside in the same coordinate system, and the initial alignment is "close" to the desired results. - -Another case is when the two datasets are from the "same" family of objects - for example, running the example with two types of sharks that exist in different coordinate systems. - -The algorithm proceeds as follows: - -1. Read the two vtkPolyData's that exist in the example's command line. The first file contains the source vtkPolyData to be aligned with the second file's vtkPolyData called the target. Another naming convention is moving and fixed. - -2. Compute a measure of fit of the two original files. We use the recently added vtkHausdorffDistancePointSetFilter to compute the measure. See [Hausdorff Distance](https://en.wikipedia.org/wiki/Hausdorff_distance). - -3. Align the bounding boxes of the two datasets. Here we use a vtkOBBTree locator to create oriented bounding boxes. See [Oriented Bounding Boxes](https://en.wikipedia.org/wiki/Minimum_bounding_box). Use the bounding box corner coordinates to create source and target vtkLandmarkTransform's. vtkTransformPolyData uses this transform to create a new source vtkPolyData. Since the orientations of the bounding boxes may differ, the AlignBoundingBoxes function tries ten different rotations. For each rotation, it computes the Hausdorff distance between the target's OBB corners and the transformed source's OBB corners. Finally, transform the original source using the smallest distance. - -4. Improve the alignment with vtkIterativeClosestPointTransform with a RigidBody transform. Compute the distance metric again. - -5. Display the source and target vtkPolyData's with the transform that has the best distance metric. - -!!! info - The example is run with `src/Testing/Data/thingiverse/Grey_Nurse_Shark.stl` and `src/Testing/Data/greatWhite.stl`, in this case, we reorient the target using a rotation. vtkTransformPolyDataFilter is used to get a better fit in this case. - -!!! info - If example is run with `src/Testing/Data/thingiverse/Grey_Nurse_Shark.stl` and `src/Testing/Data/shark.ply` the fit is really poor and the Iterative Closest Point algotithm fails. So we fallback and use oriented bounding boxes. diff --git a/data/examples/PolyData/AlignTwoPolyDatas.py b/data/examples/PolyData/AlignTwoPolyDatas.py deleted file mode 100755 index 660b854..0000000 --- a/data/examples/PolyData/AlignTwoPolyDatas.py +++ /dev/null @@ -1,416 +0,0 @@ -#!/usr/bin/env python -# -*- coding: utf-8 -*- -

A polygonal representation of a sphere is created with the source object (vtkSphereSource). The sphere is passed through a filter (vtkElevationFilter) that computes the height of each point of the sphere above a plane. The plane is perpendicular to the z-axis, and passes through the point (0,0,-1). The data is finally mapped (vtkDataSetMapper) through a lookup table. The mapping process converts height value into colors, and interfaces the sphere geometry to the rendering library. The mapper is assigned to an actor, and then the actor is displayed. - -The execution of the pipeline occurs implicitly when we render the actor. Each actor asks its mapper to update itself. The mapper in turn asks its input to update itself. This process continues until a source object is encountered.

Textures are used to set base color, ORM, emissivity and normals. Textures for the image based lighting and the skymap are supplied from a cubemap. - -Image based lighting uses a cubemap texture to specify the environment. A Skybox is used to create the illusion of distant three-dimensional surroundings. Textures for the image based lighting and the skybox are supplied from an HDR or JPEG equirectangular Environment map or cubemap consisting of six image files. - -A good source for Skybox HDRs and Textures is [Poly Haven](https://polyhaven.com/all). Start with the 4K HDR versions of Skyboxes. - -The parameters used to generate the example image are loaded from a JSON file with the same name as the example. In this case: - -``` text -/PBR_Skybox_Texturing.json -``` - -Where `` is the path to `?vtk-?examples/src/Testing/Data`. - -By default we use the equirectangular file to generate the texture for the lighting and skybox. We have optionally provided six individual cubemap files to generate lighting and a skybox. - -For information about the parameters in the JSON file, please see [PBR_JSON_format](../../Documentation/PBR_JSON_format.md). - -### Options - -``` text -Positionals: - fileName The path to the JSON file containing the parameters. - -Options: - -h,--help Print this help message and exit - -s,--surface The name of the surface.

This allows you to copy this JSON file and the associated subfolders to any other location on your computer. - - You can turn off the skybox in the JSON file by setting `"skybox":false`. Image based lighting will still be active. - -!!! note - - The C++ example requires C++17 as `std::filesystem` is used.

The transform filter only operates on objects with explicit point coordinate representation (i.e., a subclass of vtkPointSet ). However, the elevation filter generates the more general form vtkDataSet as output. Hence we cannot connect the transform filter to the elevation filter. But we can connect the transform filter to the sphere source, and then the elevation filter to the transform filter.

-Extrusion blow molding process. - -In the extrusion blow molding process, a material is extruded through an annular die to form -a hollow cylinder. This cylinder is called a parison. Two mold halves are then closed on the parison, while at the same time the parison is inflated with air. -Some of the parison material remains within the mold while some becomes waste material. -The material is typically a polymer plastic softened with heat, but blow molding has been used to form metal parts. Plastic bottles are often manufactured using a blow molding process. - -In this example the polymer was molded using an isothermal, nonlinear-elastic, incompressible (rubber-like) material. Triangular membrane finite elements were used to model the parison, while a combination of triangular and quadrilateral finite elements were used to model the mold. The mold surface is assumed to be rigid, and the parison is -assumed to attach to the mold upon contact. Thus the thinning of the parison is controlled by its stretching during inflation and the sequence in which it contacts the mold. - -Ten steps of the analysis are illustrated. The color of the parison indicates its thickness. Using a rainbow scale, red areas are thinnest while blue regions are thickest. Our visualization shows clearly one problem with the analysis technique we are using. Note that while the nodes (i.e., points) of the finite element mesh are prevented from passing through the mold, the interior of the -triangular elements are not. This is apparent from the occlusion of the mold wireframe by the parison mesh. - -You can also view the individual steps. - -!!! info - See [Figure 12-17](../../../VTKBook/12Chapter12/#Figure%2012-17) in [Chapter 12](../../../VTKBook/12Chapter12) the [VTK Textbook](../../../VTKBook/01Chapter1). diff --git a/data/examples/Visualization/Blow.py b/data/examples/Visualization/Blow.py deleted file mode 100755 index 3da01a3..0000000 --- a/data/examples/Visualization/Blow.py +++ /dev/null @@ -1,176 +0,0 @@ -#!/usr/bin/env python -

-In this example we are coloring the surface by partitioning the gaussian curvature into bands and using arrows to display the normals on the surface. - -Rather beautiful surfaces are generated. - -The banded contour filter and an indexed lookup table are used to generate the curvature bands on the surface. To further enhance the surface, the surface normals are glyphed and colored by elevation using a diverging lookup table. - -Note that: - -- If the regions on a surface have zero Gaussian curvature, then they can be flattened into a plane with no distortion, and the geometry of the region is Euclidean geometry. - -- If the regions on a surface have positive Gaussian curvature, then the geometry of the surface is spherical geometry. - -- If the regions on the surface have a negative Gaussian curvature, then the geometry of the surface is hyperbolic geometry. - -In the above image you can see that the random hills incorporate all of these geometries. - -The surface selected is the parametric random hills surface. The problem with the random hills surface is: - -- Most of the gaussian curvatures will lie in the range -1 to 0.2 (say) with a few large values say 20 to 40 at the peaks of the hills. -- The edges of the random hills surface also have large irregular values so we need to handle these also. In order to fix this, a function is provided to adjust the edges. - -So we need to manually generate custom bands to group the curvatures. The bands selected in the examples show that the surface is mostly planar with some hyperbolic regions (saddle points) and some spherical regions. - -Feel free to experiment with different color schemes and/or the other sources from the parametric function group or the torus etc. - -You will usually need to adjust the parameters for `maskPts`, `arrow` and `glyph` for a nice appearance. - -A histogram of the frequencies is also output to the console. This is useful if you want to get an idea of the distribution of the scalars in each band. diff --git a/data/examples/Visualization/CurvatureBandsWithGlyphs.py b/data/examples/Visualization/CurvatureBandsWithGlyphs.py deleted file mode 100755 index 3d07c3a..0000000 --- a/data/examples/Visualization/CurvatureBandsWithGlyphs.py +++ /dev/null @@ -1,1077 +0,0 @@ -#!/usr/bin/env python -

The goal of the puzzle is to move the disks from one peg to another, moving the disks one at a time, and never placing a larger disk on top of a smaller disk. - -Here we first set up the scene with the table, pegs and pucks. Then we use a function called `Hanoi()` to begin the recursion. A second function `MovePuck()` moves the puck from one peg to another. - -To give a pleasing visual effect we move the disk in small, user-specified increments, flipping the disc over as it moves -from one peg to the next. Option `-s` controls the user-defined increments. The option `-c 2` freezes a disk in mid air moving from one peg to another. - -!!! info - See [Figure 12-20c](../../../VTKBook/12Chapter12/#Figure%2012-20c) in [Chapter 12](../../../VTKBook/12Chapter12) the [VTK Textbook](../../../VTKBook/01Chapter1). diff --git a/data/examples/Visualization/Hanoi.py b/data/examples/Visualization/Hanoi.py deleted file mode 100755 index bc38a4b..0000000 --- a/data/examples/Visualization/Hanoi.py +++ /dev/null @@ -1,391 +0,0 @@ -#!/usr/bin/env python - -# Translated from Hanoi.cxx. - -# noinspection PyUnresolvedReferences -import vtkmodules.vtkInteractionStyle -# noinspection PyUnresolvedReferences -import vtkmodules.vtkRenderingOpenGL2 -from vtkmodules.vtkCommonColor import vtkNamedColors -from vtkmodules.vtkCommonCore import vtkMinimalStandardRandomSequence -from vtkmodules.vtkFiltersSources import ( - vtkCylinderSource, - vtkPlaneSource -) -from vtkmodules.vtkIOImage import ( - vtkBMPWriter, - vtkJPEGWriter, - vtkPNGWriter, - vtkPNMWriter, - vtkPostScriptWriter, - vtkTIFFWriter -) -from vtkmodules.vtkRenderingCore import ( - vtkActor, - vtkCamera, - vtkPolyDataMapper, - vtkRenderWindow, - vtkRenderWindowInteractor, - vtkRenderer, - vtkWindowToImageFilter -) - - -class GV(object): - """ - Used to store global variables. - """ - - def __init__(self, numberOfPucks=5, numberOfSteps=5, puckResolution=48, configuration=0): - self.numberOfPucks = numberOfPucks - self.numberOfSteps = numberOfSteps - self.puckResolution = puckResolution - self.configuration = configuration - self.gotFigure2 = False # Used to bail out of recursion if configuration == 2. - self.L = 1.0 # Puck height. - self.H = 1.1 * self.numberOfPucks * self.L # Peg height. - self.R = 0.5 # Peg radius. - self.rMin = 4.0 * self.R # The minimum allowable radius of disks. - self.rMax = 12.0 * self.R # The maximum allowable radius of disks - self.D = 1.1 * 1.25 * self.rMax # The distance between the pegs. - self.numberOfMoves = 0 - - def update(self, numberOfPucks, numberOfSteps, puckResolution, configuration): - self.numberOfPucks = numberOfPucks - self.numberOfSteps = numberOfSteps - self.puckResolution = puckResolution - self.configuration = configuration - self.H = 1.1 * self.numberOfPucks * self.L # Peg height. - - -# Globals -gv = GV() -renWin = vtkRenderWindow() -""" - For pegStack we use a list of lists where the sublists correspond to the - source, target and helper pegs. - Python lists can be used as a stack since they have append() (corresponding - to push()) and pop(). -""" -pegStack = [[], [], []] - - -def hanoi(): - colors = vtkNamedColors() - - # Create the renderer and render window interactor. - ren = vtkRenderer() - renWin.AddRenderer(ren) - renWin.SetSize(1200, 750) - iren = vtkRenderWindowInteractor() - iren.SetRenderWindow(renWin) - - ren.SetBackground(colors.GetColor3d('PapayaWhip')) - - camera = vtkCamera() - camera.SetPosition(41.0433, 27.9637, 30.442) - camera.SetFocalPoint(11.5603, -1.51931, 0.95899) - camera.SetClippingRange(18.9599, 91.6042) - camera.SetViewUp(0, 1, 0) - - ren.SetActiveCamera(camera) - - # Create geometry: table, pegs, and pucks. - pegGeometry = vtkCylinderSource() - pegGeometry.SetResolution(8) - pegMapper = vtkPolyDataMapper() - pegMapper.SetInputConnection(pegGeometry.GetOutputPort()) - - puckGeometry = vtkCylinderSource() - puckGeometry.SetResolution(gv.puckResolution) - puckMapper = vtkPolyDataMapper() - puckMapper.SetInputConnection(puckGeometry.GetOutputPort()) - - tableGeometry = vtkPlaneSource() - tableGeometry.SetResolution(10, 10) - tableMapper = vtkPolyDataMapper() - tableMapper.SetInputConnection(tableGeometry.GetOutputPort()) - - # Create the actors: table top, pegs, and pucks - # The table - table = vtkActor() - ren.AddActor(table) - table.SetMapper(tableMapper) - # table.GetProperty().SetColor(0.9569, 0.6431, 0.3765) - table.GetProperty().SetColor(colors.GetColor3d('SaddleBrown')) - table.AddPosition(gv.D, 0, 0) - table.SetScale(4 * gv.D, 2 * gv.D, 3 * gv.D) - table.RotateX(90) - - # The pegs (using cylinder geometry).

The room has two windows, a door(with air leakage), and a cooking area with a hot stove. The air leakage and temperature variation combine to produce air convection currents throughout the kitchen. The starting positions of the streamlines were defined by creating a rake, or curve (and its associated points). Here the rake was a straight line modeled with a vtkLineSource. These streamlines clearly show features of the flow field. By releasing many streamlines simultaneously we obtain even more information, as the eye tends to assemble nearby streamlines into a “global” understanding of flow field features. - -!!! info - See [Figure 6-18](../../../VTKBook/06Chapter6/#Figure%206-18) in [Chapter 6](../../../VTKBook/06Chapter6) the [VTK Textbook](../../../VTKBook/01Chapter1). diff --git a/data/examples/Visualization/Kitchen.py b/data/examples/Visualization/Kitchen.py deleted file mode 100755 index 65fe207..0000000 --- a/data/examples/Visualization/Kitchen.py +++ /dev/null @@ -1,331 +0,0 @@ -#!/usr/bin/env python -

-This example generates streamtubes of blood velocity. an isosurface of speed provides context. The starting positions for the streamtubes were determined by experimenting with the data. Because of the way the data was measured and the resolution of the velocity field, many streamers travel outside the artery. This is because the boundary layer of the blood flow is not captured due to limitations in data resolution. Consequently, as the blood flows around curves, there is a component of the velocity field that directs the streamtube outside the artery. As a result it is hard to find starting positions for the streamtubes that yield interesting results. The examples uses the source object vtkPointSource in combination with vtkThresholdPoints to work around this problem. vtkPointSource generates random points centered around a sphere of a specified radius. We need only find an approximate position for the starting points of the streamtubes and then generate a cloud of random seed points. vtkThresholdPoints is used to cull points that may be generated outside the regions of high flow velocity. -

-Clipping is implemented in vtkClipPolyData . Each polygonal data primitive implements the operation in its Clip() method using case tables. vtkClipPolyData has methods to control whether an implicit function provides the scalar data or whether the dataset’s scalar data will be used. Compute*ScalarDataOn()* uses the implicit function and *ComputeScalarDataOff()* uses the dataset’s scalar data. Two output polygonal datasets are produced. These are accessed with *GetOutput()* and *GetClippedOutput()* methods. *GetOutput()* returns the polygonal data that is “inside” the clipping region while *GetClippedOutput()* returns polygonal data that is “outside” the region. (Note that *GenerateClippedOutputOn()* must be enabled if you are to get the clipped output.) The meaning of inside and outside can be reversed using the *InsideOutOn()*. - -This example shows a plane of quadrilaterals clipped with a boolean implicit function. - -!!! info - See [Figure 9-48](../../../VTKBook/09Chapter9/#Figure%209-48) in [Chapter 9](../../../VTKBook/09Chapter9) The [VTK Textbook](../../../VTKBook/01Chapter1). diff --git a/data/examples/VisualizationAlgorithms/ClipSphereCylinder.py b/data/examples/VisualizationAlgorithms/ClipSphereCylinder.py deleted file mode 100755 index 0eefcaf..0000000 --- a/data/examples/VisualizationAlgorithms/ClipSphereCylinder.py +++ /dev/null @@ -1,119 +0,0 @@ -#!/usr/bin/env python -

In particular it uses the region separation property to select data. Selecting or extracting data with an implicit function means choosing cells and points (and associated attribute data) that lie within a particular region of the function. To determine whether a point x-y-z lies within a region, we simply evaluate the point and examine the sign of the result. A cell lies in a region if all its points lie in the region. Here, two ellipses are used in combination to select voxels within a volume dataset. Note that extracting data often changes the structure of the dataset. In this example the input type is a image data dataset, while the output type is an unstructured grid dataset. - -!!! info - See [Figure 6-24](../../../VTKBook/06Chapter6/#Figure%206-24) in [Chapter 6](../../../VTKBook/06Chapter6) the [VTK Textbook](../../../VTKBook/01Chapter1). diff --git a/data/examples/VisualizationAlgorithms/ExtractData.py b/data/examples/VisualizationAlgorithms/ExtractData.py deleted file mode 100755 index 92d8164..0000000 --- a/data/examples/VisualizationAlgorithms/ExtractData.py +++ /dev/null @@ -1,108 +0,0 @@ -#!/usr/bin/env python - -# noinspection PyUnresolvedReferences -import vtkmodules.vtkInteractionStyle -# noinspection PyUnresolvedReferences -import vtkmodules.vtkRenderingOpenGL2 -from vtkmodules.vtkCommonColor import vtkNamedColors -from vtkmodules.vtkCommonDataModel import ( - vtkImplicitBoolean, - vtkQuadric, - vtkSphere -) -from vtkmodules.vtkCommonTransforms import vtkTransform -from vtkmodules.vtkFiltersExtraction import vtkExtractGeometry -from vtkmodules.vtkFiltersGeneral import vtkShrinkFilter -from vtkmodules.vtkFiltersModeling import vtkOutlineFilter -from vtkmodules.vtkImagingHybrid import vtkSampleFunction -from vtkmodules.vtkRenderingCore import ( - vtkActor, - vtkDataSetMapper, - vtkPolyDataMapper, - vtkRenderWindow, - vtkRenderWindowInteractor, - vtkRenderer -) - - -def main(): - colors = vtkNamedColors() - - ren1 = vtkRenderer() - - renWin = vtkRenderWindow() - renWin.AddRenderer(ren1) - - iren = vtkRenderWindowInteractor() - iren.SetRenderWindow(renWin) - - quadric = vtkQuadric() - quadric.SetCoefficients(0.5, 1, 0.2, 0, 0.1, 0, 0, 0.2, 0, 0) - - sample = vtkSampleFunction() - sample.SetSampleDimensions(50, 50, 50) - sample.SetImplicitFunction(quadric) - sample.ComputeNormalsOff() - - trans = vtkTransform() - trans.Scale(1, 0.5, 0.333) - - sphere = vtkSphere() - sphere.SetRadius(0.25) - sphere.SetTransform(trans) - - trans2 = vtkTransform() - trans2.Scale(0.25, 0.5, 1.0) - - sphere2 = vtkSphere() - sphere2.SetRadius(0.25) - sphere2.SetTransform(trans2) - - booleanUnion = vtkImplicitBoolean() - booleanUnion.AddFunction(sphere) - booleanUnion.AddFunction(sphere2) - booleanUnion.SetOperationType(0) # boolean Union - - extract = vtkExtractGeometry() - extract.SetInputConnection(sample.GetOutputPort()) - extract.SetImplicitFunction(booleanUnion) - - shrink = vtkShrinkFilter() - shrink.SetInputConnection(extract.GetOutputPort()) - shrink.SetShrinkFactor(0.5) - - dataMapper = vtkDataSetMapper() - dataMapper.SetInputConnection(shrink.GetOutputPort()) - dataActor = vtkActor() - dataActor.SetMapper(dataMapper) - - # outline - outline = vtkOutlineFilter() - outline.SetInputConnection(sample.GetOutputPort()) - - outlineMapper = vtkPolyDataMapper() - outlineMapper.SetInputConnection(outline.GetOutputPort()) - - outlineActor = vtkActor() - outlineActor.SetMapper(outlineMapper) - outlineActor.GetProperty().SetColor(0, 0, 0) - - # Add the actors to the renderer, set the background and size - # - ren1.AddActor(outlineActor) - ren1.AddActor(dataActor) - ren1.SetBackground(colors.GetColor3d("SlateGray")) - - renWin.SetSize(640, 480) - renWin.SetWindowName('ExtractData') - - renWin.Render() - ren1.GetActiveCamera().Azimuth(30) - ren1.GetActiveCamera().Elevation(30) - - renWin.Render() - iren.Start() - - -if __name__ == '__main__': - main() diff --git a/data/examples/VisualizationAlgorithms/FlyingHeadSlice.md b/data/examples/VisualizationAlgorithms/FlyingHeadSlice.md deleted file mode 100644 index d82f47e..0000000 --- a/data/examples/VisualizationAlgorithms/FlyingHeadSlice.md +++ /dev/null @@ -1,8 +0,0 @@ -### Description - -This example generates 2D contour lines on one CT slice through the head.

-This is an example of texture clipping using a transparent texture map. The motor shown consists of five complex parts, some of which are hidden by the outer casing. To see the inside of the motor, we define an implicit clipping function. This function is simply the intersection of two planes to form a clipping "corner". The object **vtkImplicitTextureCoords** is used in combination with this implicit function to generate texture coordinates. These objects are then rendered with the appropriate texture map and the internal parts of the motor can be seen. - -The texture map consists of three regions (as described previously in the chapter). The concealed region is transparent. The transition region is opaque but with a black (zero intensity) color. The highlighted region is full intensity and opaque. As can be seen from the result , the boundaries appear as black borders giving a nice visual effect. - -Note the use of vectors in the C++ version and lists in the Python version to reduce repetitious code. -

The dataset is a volume of dimensions 256^3. The data is of the root system of a small pine tree. Using the class vtkSliceCubes , an implementation of marching cubes for large volumes, we generate an initial isosurface represented by 351,536 triangles. This is a faster way of manipulating this data. If you have a large enough computer you can process the volume directly with a vtk image reader and vtkMarchingCubes. -[The example on this other page](../PineRootConnectivityA) shows the initial dataset. Notice that there are many small, disconnected isosurfaces due to noise and isolated moisture in the data. We use vtkConnectivityFilter to remove these small, disconnected surfaces. The example on this page shows the result of applying the filter. Over 50,000 triangles were removed, leaving 299,380 triangles. The vtkConnectivityFilter is a general filter taking datasets as input, and generating an unstructured grid as output. It functions by extracting cells that are connected at points (i.e., share common points). In this example the single largest surface is extracted. It is also possible to specify cell ids and point ids and extract surfaces connected to these. - -!!! info - To count the number of triangles in the polydata we do the following: - #### C++ - We use a lambda function - ``` c++ - auto NumberofTriangles = [](auto *pd) - ``` - #### Python - We just implement: - ``` python - def NumberOfTriangles(pd): - ``` - within the scope of the calling function. - -!!! cite - *Comparative Water Uptake by Roots of Different Ages in Seedlings of Loblolly Pine (Pinus taeda L.)* December 1991.

Probing is also called “resampling.” Examples include probing an input dataset with a sequence of points along a line, on a plane, or in a volume. The result of the probing is a new dataset (the output) with the topological and geometric structure of the probe dataset, and point attributes interpolated from the input dataset. Once the probing operation is completed, the output dataset can be visualized with any of the appropriate techniques in VTK. - -This example illustrates the details of the probing process. For every point in the probe dataset, the location in the input dataset (i.e., cell, subcell, and parametric coordinates) and interpolation weights are determined. Then the data values from the cell are interpolated to the probe -point. Probe points that are outside the input dataset are assigned a nil (or appropriate) value.
