Hello,
I am trying to determine the bounding sphere for a node in the scene
graph... but it is always returned as 0,0,0. Here's the code:
pfSphere objSphere;
dcs->setBound( NULL, PFBOUND_STATIC ); //should force pf to recompute
dcs->getBound( &objSphere ); //get the sphere
pfVec3 objCenter = objSphere.center;
dcs->setTrans( -objCenter[0], -objCenter[1], -objCenter[2] );
The pfVec3 objCenter should contain the center point of the heirarchy in
world coordinates, right? The dcs node should also be repositioned with
its center at the origin. Geodes and other children have already been
added under the dcs node, but is there something additional I need to do
in order to ensure the bounding sphere takes them into account? I know
that 0,0,0 isn't correct for the center because I have manually offset the
dcs position earlier.
Any help would be appreciated. Thanks!
-Chris
