After quite a long time now xBIM can visualize textures. Hence, issue #140 and #127 are solved.
Texturing a geometry hardly depends on the geometry. For a simple and general approach i decided to use a spherical texturing https://de.wikipedia.org/wiki/UV-Koordinaten. This approach can lead to distortion and artifacts. Hence, other approaches shall be implemented in future.
For the architecture I decided to add a new directory to the Presentation library: texturing. This contains an Interface
ITextureMappingand the classSphericalTextureMapto calculate the texture mapping.To decide whether the texture coordinates have to be calculated, I had to add some small reflections. Maybe there is a better way for checking of a texture coordinate.
