AllocateAndMergeBufferObjectsVisitor::apply(osg::Drawable& drawable)
{
osg::Geometry* geom = drawable.asGeometry();
if ( geom )
{
// We disable vbo's and then re-enable them to enable sharing of all the arrays.
geom->setUseDisplayList( false );
geom->setUseVertexBufferObjects( false );
geom->setUseVertexBufferObjects( true );
}
traverse(drawable);
