Hi, here is an example to show you how you can change the properties of a
pre-loaded object. My example is for the ENLIGHTING state but it's the
same for the others states (see the pfGStateMode man page).
In my example, this is a simple case where my node has only one pfgeode. In
a general case you must write a function to find the pfgeode.
void
change_3D_model_property (char *p_node_name)
{
pfNode *l_node;
pfGeoState *l_gstate;
pfGeoSet *l_gset;
pfGeode *l_geode;
l_node = pfLookupNode(p_node_name, pfGetNodeClassType()); /*get the
node*/
l_geode = pfGetChild (l_node ,0); /*in my case it's simple, only one
pfgeode which is child of pfnode, in your case write a function to get all
pfgeode of the node*/
l_gset = pfGetGSet (l_geode, 0); /* get the gset*/
l_gstate = pfGetGSetGState (l_gset); /* get the gstate of the gset*/
pfGStateMode (l_gstate, PFSTATE_ENLIGHTING, PF_OFF); /*change the
gstate*/
}
Hope it can help you,
Cheers,
