Hi everyone I hope I''ll find someone who can help me out, here.. We are about writing a game in Java(3D). For gaining some speed we decided to use pre - rendered background images and to only implement some items and the characters as real 3d objects. So we took our 800 * 600 pixel Image, loaded it into background, put some objects in and - it looked wrong. It seems, Java3D always renders with the field of view equal in horizontal and vertical... So I had a look at the API doc and found something called ''compatibility mode''. Well - after having defined a new frustum with the perspective() - method in Transform3d, it seemed to turn out right. But - now our picking doesn''t work anymore. Anyone an idea how we have to solve it so that both (different fov and picking) are running.. ?

I had very little luck writting a game in Java 3D. Even with simple scenes I was encountering massive memory requirements and an occasional world freeze that I attributed to either lack of memeory (I have 128 MB in my system) or garbage collection kicking off at inopportune times.

Of course, I am NO WHERE NEAR an expert in Java 3D, so it could have simply been my ineptitude as a developer. I would really appreciate it if you could share some of your experiences with using Java 3D in game development.

Thanks,

Now, i wouldn''t describe me as an expert in Java3d, too..
In fact I am a student in computer science at the biel, school of ingeneering, switzerland (http://www.hta-bi.bfh.ch) who took the course computer graphics and has to write a semester work in java3d now...

The game idea resulted from the fact, that we love playing games and decided we were able to do one, too - but - ''it''s my first time''.

Naturally I''ll gladly share my experience, as soon as i have some more
