I’m new to jaa game programming(thats why I’m posting in this forum int the first place ;D).As far as I know there 2 ways to implement 3d graphics in java which is jogl and j3d. what want to know is what is good for what.
Also, LWJGL (http://www.lwjgl.org).
There is also jME (Java Monkey Engine) (http://www.jmonkeyengine.com)
LWJGL and JOGL are OpenGL bindings for Java.
Java3D is a scenegraphy 3D library.
jME is a scenegraphy 3D game engine.
Many ways to do 3D graphics, but they all use the same fundamentals. I recommend studying those fundamentals first, then you can easily adopt any of those ^ libraries/engines.
