So, as promised here's the code to strip textures and UV coords from geometry.
It saves me about 700 mb at runtime, which makes me happy :o
Code:
class StripTexturesVisitor : public osg::NodeVisitor
{
public:
StripTexturesVisitor()
: osg::NodeVisitor(osg::NodeVisitor::TRAVERSE_ALL_CHILDREN)
{}
void Strip(osg::Drawable* drawable)
{
osg::Geometry* geometry = drawable->asGeometry();
osg::StateSet* ss = drawable->getStateSet();
if(ss != NULL)
{
for(unsigned int i = 0; i < 2; ++i)
{
ss->removeTextureAttribute(i, osg::StateAttribute::TEXTURE);
if(geometry != NULL)
{
geometry->setTexCoordArray(i, NULL);
}
}
ss->releaseGLObjects();
}
}
virtual void apply(osg::Geode& node)
{
for(unsigned int i = 0; i < node.getNumDrawables(); ++i)
{
Strip(node.getDrawable(i));
}
traverse(node);
}
};
