i totally forgot to stop the computation before going to works so it kept adding more and more points after many hours smiley)
I'm glad to report that with 13 Millions voxel the graphic card is not even stressed (the cpu and system ram, however, is).

Here it is :

If you're interested in parallel computing on the JVM you might be interested in the programming language Clojure.

indeed smiley

Well, not stressed because the Cpu is the bottleneck and the gpu have no problem displaying this at ~1FPS.
However, if i stop the computation then the gfx card will try to display it as fast as possible and, of course, will stress.
The code (including the openGL part) is still very inneficient smiley

Ooooooooooold stuff. I'm planning to rewrite this.

I was searching if there was any progress with 3D buddhabrot and all i can find is my own stuff.
Well... back to work  grin
