hi Laurens.
Thank you for the your reply.
I've tried adding dirty() and it still doesn't work.
Code:
virtual void operator()(osg::Node*, osg::NodeVisitor* nv)
{
if (nv->getFrameStamp())
{
_coord =
dynamic_cast<osg::Vec2Array*>(_geom->getTexCoordArray(0));
if (_coord)
{
for (unsigned int u = 0; u < _coord->size(); u++)
{
_coord->at(u).x() += 0.01f;
_coord->at(u).y() += 0.01f;
_coord->dirty();
_geom->dirtyDisplayList();
}
}
}
}
What should I do more?
