Socket Print

A utility CAD-like application to apply modifications to a prosthetic limb socket STL file, and output the modifications to a GCode file.

Testing

In order to test GCode files, use the NCViewer website.

Coordinate System Transformation

This application bridges two different coordinate system conventions:

• Three.js (3D visualization): Y-up coordinate system where Y is the vertical axis
• 3D Printing/GCode: Z-up coordinate system where Z is the vertical axis

Why This Matters

When generating GCode from Three.js geometries, coordinate transformations are necessary to convert between these systems:

1. In Three.js: Objects are positioned with Y representing height
2. In GCode: The Z axis represents height (vertical movement)

Where Transformations Occur

• generateGCode.ts: The makeGCodePoint() function (line 42-50) and flipVerticalAxis() function (line 38-40) handle the Y↔Z axis transformations when converting Three.js Vector3 points to GCode coordinates
• sliceWorker.ts: Points are collected in Three.js coordinate space (Y-up) and later transformed during GCode generation

When reading the code, keep in mind that variables like verticalAxis and flipHeight are used to manage this coordinate system transformation throughout the pipeline.
