It sounds like you need the WalkViewerBehavior that was written by Henry Sowizral and Dave Nadeau: http://www.sdsc.edu/~nadeau/Courses/Siggraph99/ The website includes a very good tutorial on Java3D and WalkViewerBehavior.java is a class that moves the view based on mouse movements to emulate the

Hi Vadim,   Unfortunately, I don't have a solution for your problem. I've seen it too, although on my kind of application it doesn't have any importance, so I was happy to ignore it.   However, I have noticed that the time to add / remove an object from a live scenegraph depends very much on the

Wether the scene or the camera moves is just a matter of where the behaviour is attached. Attach it to the viewplatform and the camera moves. Using KeyNavBehaviour and sich is a predefined service (that you don't actually have in OGL/DirectX). Of cource you can implement your own movement. This ca

Dear all, I am wondering how to implement a smooth walking through in a 3D scene in Java3D. Suppose the 3D scene has been constructed, if I use mouse behavior(MouseRotate etc) and/or KeyNavigatorBehavior, it looks like that the 3D scene is being rotated, translated, not like I am walking through i
