unsigned int numOriginalPrimitives,

unsigned int numRemainingPrimitives

) const [inline]

virtual bool osgUtil::Simplifier::continueSimplificationImplementation ( float nextError,

unsigned int numOriginalPrimitives,

unsigned int numRemainingPrimitives

) const [inline, virtual]

const ContinueSimplificationCallback* osgUtil::Simplifier::getContinueSimplificationCallback ( ) const [inline]

ContinueSimplificationCallback* osgUtil::Simplifier::getContinueSimplificationCallback ( ) [inline]

bool osgUtil::Simplifier::getDoTriStrip ( ) const [inline]

float osgUtil::Simplifier::getMaximumError ( ) const [inline]

float osgUtil::Simplifier::getMaximumLength ( ) const [inline]

float osgUtil::Simplifier::getSampleRatio ( ) const [inline]

bool osgUtil::Simplifier::getSmoothing ( ) const [inline]

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.

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.
