void osgUtil::Simplifier::setMaximumError float  error  )  [inline]
 

Set the maximum point error that all point removals must be less than to permit removal of a point. Note, Only used when down sampling. i.e. sampleRatio < 1.0

void osgUtil::Simplifier::setMaximumLength float  length  )  [inline]
 

Set the maximum length target that all edges must be shorted than. Note, Only used when up sampling i.e. sampleRatio > 1.0.

void osgUtil::Simplifier::setSampleRatio float  sampleRatio  )  [inline]
 

void osgUtil::Simplifier::setSmoothing bool  on  )  [inline]
 

void osgUtil::Simplifier::simplify osg::Geometry geometry,
const IndexList protectedPoints
 

a list of point indices

simply the geometry, whilst protecting key points from being modified.

void osgUtil::Simplifier::simplify osg::Geometry geometry  ) 
 

simply the geometry.
