I’m confused as to the difference in Java3d between View, ViewPlatform and ViewingPlatform. What’s the difference and how do they get used together?

Thanks :smiley:

Roughly, trying to remember…

View is a thing like a camera. ViewPlatform is kind of a camera mount located somewhere in the scenegraph, ViewingPlatform is a utility class tying those things together. Roughly…

Thanks, managed to find a little more info on it, I seem you’re right, roughly, lol. Gonna have a play round… :smiley:

If you do manage to acquire a complete understanding, please do explain for the rest of the world. Especially how the various transform groups involved work.

I get so baffled by all the calls to ViewingPlatform.GetViewPlatform.GetViewingPlatformTransform().GetViewPlatformTransform().GetViewTransform().GetMagicalExtraTransform().GetSomeKindOfSpecialInexplicableTransform() or whatever it is.

I always add the ViewPlatform to a TransformGroup. Which in tern a View object is attached to the ViewPlatform. I modify that first TransformGroup to move the camera around. That seems to be the only thing you can do.

There is a method in ViewPlatform that returns a TransformGroup; however, it says it gets the bottom-most TransformGroup associated with this ViewPlatform. If you keep a refernce to the TransformGroup that u added the ViewPlatform to, then it should be the same as what is returned in that method (

getViewPlatformTransform()

).

I think thats all there is too it … feel free to add if I am missing something.
