public class SoUniformGridProjectionClipping extends SoUniformGridClipping
Clips a volume with the depth map projection of a shape. This class is an helper class derived from SoUniformGridClipping. It defines its clipping texture by the depth map of the given sceneGraph in the given axis orientation.

Notes:

  • Rendering the sceneGraph on top of the clipped volume might result in z-fighting artefacts due to depth precision. In order to avoid this issue it is necessary to use a SoPolygonOffset node before the geometry to render.
  • sceneGraph should not contain any draggers or manipulators because they will become part of the clipping texture and might lead to unwanted results. As a workaround, you can put draggers outside of sceneGraph, put an SoTransform inside your sceneGraph and connect it to your dragger.
  • If sceneGraph contains holes, you should set the minFilter and magFilter fields to NEAREST to avoid interpolation issues between holes and the true surface.
  • The inherited field SoUniformGridClipping.undefinedValue is set to the default depth (i.e. 1).

See SoUniformGridClipping for detailed behavior and limitations.
