Hi,
I see the two lines in octTree() is comment out
transInterpolator.setEnable(false);
rotatorInterpolator.setEnable(false);
when I uncomment the lines, it throws:
Exception occurred during Behavior execution:
java.lang.NullPointerException
at TMove.octTree(TMove.java:243)
at TMove.octTree(TMove.java:411)
at TMove.octTree(TMove.java:427)
at TMove.octTree(TMove.java:427)
at TMove.octTree(TMove.java:427)
at TMove.processStimulus(TMove.java:171)
at javax.media.j3d.BehaviorScheduler.doWork(BehaviorScheduler.java:167)
at javax.media.j3d.J3dThread.run(J3dThread.java:256)
when the two shape collide.
In Tetrahedron, you have
tetra.setCoordinates(0, pnts);
tetra.setColors(0, clrs);
To set the normal in tetrahedon, you can use
one of the
public void setNormal(int index, float normal[])
public void setNormal(int index, Vector3f normal)
etc..
API under GeomtryArray.java
Thanks.
