Just put it in a leaf's pre-draw callback, and possibly restore it in a
post-draw callback.
If 'leaf' is the variable name of your ssgVtxTable, define/set a pre-draw
callback once as follows:
int leaf_pre_cb( ssgEntity *obj )
{
// do whatever
glPolygonOffset( ... );
return TRUE; // otherwise the leaf doesn't get drawn
}
// in your scene graph initialization code
leaf->setCallback( SSG_CALLBACK_PREDRAW, leaf_pre_cb );
The post-draw callback can be defined/set exactly the same (post in place of
pre).
