Detailed Description
Encapsulates an algorithm for simplifying shapes through mesh decimation.
This class implements a mesh decimation algorithm for simplifying shapes.
Not all geometry nodes can be decimated. The following geometry nodes are decimated:
- SoFaceSet
- SoIndexedFaceSet
- SoIndexedNurbsSurface
- SoIndexedTriangleStripSet
- SoNurbsSurface
- SoTriangleStripSet
- SoVRMLIndexedFaceSet
The following geometry nodes are not decimated:
- SoAnnoText3
- SoAsciiText
- SoCone
- SoCube
- SoCylinder
- SoIndexedLineSet
- SoIndexedNurbsCurve
- SoLineSet
- SoNurbsCurve
- SoPointSet
- SoQuadMesh
- SoSphere
- SoText2
- SoText3
- SoVRMLBox
- SoVRMLCone
- SoVRMLElevationGrid
- SoVRMLExtrusion
- SoVRMLIndexedLineSet
- SoVRMLPointSet
- SoVRMLSphere
- SoVRMLText
- Any geometry under an SoLOD
- Any geometry under an SoLevelOfDetail
- Any geometry under an SoLevelOfSimplification
- Any geometry under an SoVRMLLOD
The decimator does not decimate nodes such as SoCone, that adjust their complexity automatically (based on SoComplexity and/or the viewer-requested decimation level). The decimator also does not decimate nodes such as SoVRMLElevationGrid where decimation would not preserve the type of geometry. Decimated geometry is always an indexed face set.
