This class is an helper class derived from OIV.VolumeViz.Nodes.SoUniformGridClipping. It defines its clipping texture by the depth map of the given OIV.VolumeViz.Nodes.SoUniformGridProjectionClipping.sceneGraph in the given axis orientation.
Notes:
Rendering the OIV.VolumeViz.Nodes.SoUniformGridProjectionClipping.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 OIV.Inventor.Nodes.SoPolygonOffset node before the geometry to render.
OIV.VolumeViz.Nodes.SoUniformGridProjectionClipping.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 OIV.VolumeViz.Nodes.SoUniformGridProjectionClipping.sceneGraph, put an OIV.Inventor.Nodes.SoTransform inside your OIV.VolumeViz.Nodes.SoUniformGridProjectionClipping.sceneGraph and connect it to your dragger.
If OIV.VolumeViz.Nodes.SoUniformGridProjectionClipping.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 OIV.VolumeViz.Nodes.SoUniformGridClipping.undefinedValue is set to the default depth (i.e. 1).
See OIV.VolumeViz.Nodes.SoUniformGridClipping for detailed behavior and limitations.
