Hi everyone, I'm wondering about a strange thing I noticed when trying to use osgUtil::pushModelViewMatrix() directly:
- Suppose I have a class where I store a ref pointer on a RefMatrix: osg::ref_ptr<osg::RefMatrix> _modelView. - Suppose in that class I have a function called during the cull traversal: draw(osgUtil::CullVisitor& cv) { osg::Matrixd mat = .... // I compute the matrix I want to use as model view here. #if STRANGE_BEHAVIOR _modelView->set(mat) cv.pushModelViewMatrix( _modelView.get(), osg::Transform::RELATIVE_RF) #else cv.pushModelViewMatrix(new osg::RefMatrix(mat), osg::Transform::RELATIVE_RF) #endif // drawing something here with a member geode object: _geode->accept(cv); cv.popModelViewMatrix(); } => If I try the "STRANGE_BEHAVIOR" section, I get nothing displayed properly (even it the OSG Stats report a good number of vertices). If I use the other section everythig is fine... Any idea what I'm missing here ?? I think it would be better if I could avoid creating a new object on the heap for each call to this function :-) cheers, Manu.
