Hi,
I got a strange thing on a double sided model...
Under Windows (XP), a line like:
stateSet->setAttributeAndModes(new
osg::CullFace(osg::CullFace::FRONT_AND_BACK), osg::StateAttribute::OFF);
disables the face culling and my model is okay.
Under Linux (Ubuntu 9.04), the *exact* same code makes all (front AND back)
faces to be culled! Thus my model is invisible.
Splitting this into 2 lines:
stateSet->setAttributeAndModes(new osg::CullFace(osg::CullFace::FRONT),
osg::StateAttribute::OFF);
stateSet->setAttributeAndModes(new osg::CullFace(osg::CullFace::BACK),
osg::StateAttribute::OFF);
makes the model visible, with the expected behaviour.
Am I wrong somewhere?
May this be a driver issue?
Is this *really* different from calling "stateset->setMode(GL_CULL_FACE,
osg::StateAttribute::OFF)" for what I want?
Any idea?
Thanks!
