Re: [Openrocket-devel] 3d Visualization

[Bill K. <bk...@bi...>]

I think you are right about Java3d. Jogl looks far better maintained, and
is the backend for Java3d now. Jogl is also one of two backend options for
JMonkeyEngine, the other option is LWJGL.

Both JOGL and LWJGL seem well maintained and documented. I made a list
comparing them but it was very boring, none of the differences were
anything interesting to OR. I think either would do, I'm inclined to keep
trying JOGL for now, the less "Game" focused of the two.

Is there any wish-list of what is desired in a 3d feature? I just thought *"3D
visualization of the rocket during design and flight (Help needed!)" *from
the web site looked like a fun idea!
