If your scene graph consists of a single Geode with a single Geometry containing a single quad primitive, I would hope and expect that the osgUtil::Simplifier wouldn't change it at all, regardless of the parameter settings. After all, the simplest way to draw a quad is to draw a quad -- it is already 100% simplified. -Paul

Okay, but, pushing this to an extreme : imagine I have a quad geometry for example, if I use a low enough ratio I shouldn't see anything left, no ? Or can't the simplifier suppress all vertices from a geometry ? Emmanuel 2007/4/10, Robert Osfield <[EMAIL PROTECTED]>: Hi Emmanuel, The osgUtil::Simplifier can only simplify individual osg::Geometry, it won't group separate geometries together and simplify them as a group.
