hi NICK.
Thank you for your reply.
I did what you tried and nothing changed.
Can you tell me another way?
Here is the code I did.
Code:
virtual void operator()(osg::Node*, osg::NodeVisitor* nv)
{
if (nv->getFrameStamp())
{
if (_coord)
{
for (unsigned int u = 0; u < _coord->size(); u++)
{
_coord->at(u).x() += 0.6f;
_coord->at(u).y() += 0.6f;
_coord->dirty();
}
_geom->setUseVertexBufferObjects(true);
_coord->getBufferObject()->dirty();
}
}
}
