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
  

The following geometry nodes are not decimated:

• SoAnnoText3
  
• SoAsciiText
  
• SoCone
  
• SoCube
  
• SoCylinder
  
• SoIndexedLineSet
  
• SoIndexedNurbsCurve
  
• SoLineSet
  
• SoNurbsCurve
  
• SoPointSet
  
• SoQuadMesh
  
• SoSphere
  
• SoText2
  
• SoText3
  
• Any geometry under an SoLOD
  
• Any geometry under an SoLevelOfDetail
  
• Any geometry under an SoLevelOfSimplification
  

The decimator does not decimate nodes such as SoCone, that adjust their complexity automatically (based on SoComplexity and/or the viewer-requested decimation level). Decimated geometry is always an indexed face set.
