Hi, In mouse bahavior(mouserotate, mousetranlate and mousezoom) class, I get a tranformgroup in public void processStimulus (Enumeration criteria) method. It seems that transform3D of this transformgroup do not corresponding to the transform3D of viewpoint, but it correspond to the origin of viewpoint. So what the relation of viewpoint's origin and scene's origin, it seems it is different. How do I get a coordinate of a object in this two coordinate system. For example, I have set a transform3D for viewpoint, it is (1,0,1) in scene's origin coordinate system but (0,0,0) in viewpoint origin system. And if I change the origin of viewpoint, how can I get the viewpoint's corrdinate in scence's system. Thank you in advance.
