OK, I feel better.
In my attempt to isolate the performer code in our app, so we can switch
to Faranheight quickly, I have developed a scene graph manager. It
should be able to turn a node on or off. Works great. Except for
pfLightSource. Here is the source code....
void sgManager::nodeOff(char* name){
pfNode* thisNode =
(pfNode*)factory->scene->find(name,pfNode::getClassType());
if(thisNode==NULL){
cout<<" Node named "<<name<<" not found. sgManager::nodeOff\n";
return;
}
thisNode->setTravMask( PFTRAV_DRAW, 0x0, PFTRAV_DESCEND, PF_SET );
}
The problem is whenever I try to turn a light source off, I get the node
not found message. I KNOW the name is right (printed it, watched it
cvd,ect).... The man page says pfLightSource isA pfNode.... what is
going on??
Here is them execution code:
sgManager::insertCoordDef("coord1",pos,scale,c);
sgManager::nodeOff("larry");
the light was created with:
{
masterChan = pfCAVEMasterChan();
scene = new pfScene;
scene->setName("scene");
navDCS = new pfDCS;
navDCS->setName("nav");
masterGeoState = new pfGeoState;
masterGeoState->setMode(PFSTATE_ENLIGHTING, PF_ON);
masterGeoState->setMode(PFSTATE_CULLFACE, PFCF_OFF);
scene->setGState(masterGeoState);
scene->addChild(navDCS);
pfLightSource* defaultLight= new pfLightSource;
defaultLight->setPos(6,0,11,0);
defaultLight->setAmbient(.3,.3,.3);
defaultLight->setName("larry");
scene->addChild(defaultLight);
masterChan->setScene(scene);
}
