GVRGeometryClipping¶

MacroModule¶

author	`MeVis Medical Solutions AG`
package	`MeVisLab/Standard`
definition	GVRGeometryClipping.def
see also	`SoGVRDepthPeel`

Purpose¶

The GVRGeometryClipping module allows for clipping the GVR volume rendering with arbitrary OpenGL geometry.

The volume inside and outside of the geometry can be colored and can have a different alpha factor. If shading is enabled, the clipping surface is shaded consistently using the surface normals of the geometry.

Usage¶

Connect this module before a SoGVRVolumeRenderer and make sure to add a SoGVRRayCastSettings module. If shading is desired, enable “Illuminated” render mode in SoGVRRayCastSettings. Connect your clipping geometry to the input of this module.

Tips¶

This module only works well together with the GVR ray caster SoGVRRayCastSettings.
