I just started in Java3D programming and i have 3 doubts to you may answer, please:
1. Is there any actual commercial project using Java3D? For example, a game project? How is the Java3D current overall status in virtual reality commercial world? There's any better option in this market niche?
2. Are there any "Java3D Certification"? In case of a positive answer, may you give some details about it?
3. Now a program problem. I wasn't able to create a program to create two bike wheels. Everything works corretly, but i have to put a Transform Group inside of another one. One is the normal one, used to rotate in Z axis. The other, however, is used to put in the correct translation. If i use only one, after rotate the first time, the whells go to point (0, 0, 0). I now that the compile method fits it, but without this, my program's initialization receive a bonus of about 50% in time. So, i would like to know if there's a way to fix it without the compile method and if the compile method is really useful in the end...
