void osgUtil::Simplifier::setContinueSimplificationCallback ( ContinueSimplificationCallback * cb ) [inline]

void osgUtil::Simplifier::setDoTriStrip ( bool on ) [inline]

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.
