[JAVA3D] PickBehaviour without utility class

[A. Murat Tanyer]

Hi all; I am trying to add 'pickBehavior' to my scene. However, the method 'updateScene(int xp, int yp)' seems to be not working. I am using the 'core ViewPlatform class': My scene's centroid is at x,y,z in the space. What I am doing is creating my viewplatform and moving it to the point near to x,y,z so that I can view the object. That means I am using the "core javax.media.j3d.ViewPlatform class" instead of the "com.sun.j3d.utils.universe.ViewingPlatform utility". I think the second one allows me using 'SimpleUniverse' and 'PickBehavior'. Is there a way adding the PickBehavior to my scene which uses VirtualUniverse? If there is no way, how can I pick my objects? Can anybody help me about this problem? Thanks Murat
