Detailed Description

VSG extension 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:

The following geometry nodes are not decimated:

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.

Member Function Documentation

◆ beginShape()

virtual void SoDecimator::beginShape ( ShapeType  )
virtual

Starts a new shape.

Shape Type defines which triangle organization to use.

Reimplemented from SoSimplifier.

◆ clear()

virtual void SoDecimator::clear ( )
virtual

Removes all shapes and reset.

Reimplemented from SoSimplifier.

◆ endShape()

virtual void SoDecimator::endShape ( )
virtual

End shape.

Reimplemented from SoSimplifier.

◆ setSimplifiedShapeType()

virtual void SoDecimator::setSimplifiedShapeType ( SoType  simplifiedShapeType)
virtual

Sets the shape type used for building the simplified node.

Only SoIndexedFaceSet and SoFaceSet are supported. SoIndexedFaceSet is used by default.

◆ setVerbosity()

virtual void SoDecimator::setVerbosity ( SbBool  v)
virtual

Verbose mode.

Reimplemented from SoSimplifier.

◆ setVertex()

virtual void SoDecimator::setVertex ( const SbVec3f )
virtual

Methods used to specify data to simplify.

Reimplemented from SoSimplifier.

◆ simplify()

virtual SoNode * SoDecimator::simplify ( float  )
virtual

Performs the simplification on the shapes and builds the simplified node.

Implements SoSimplifier.
