Also if you are using a very large model you may get precision issues
(many old threads on this) in which case:
1) using doubles instead of floats can help
2) reducing the difference between front an back clip distance can help

Check-list:
* use a good video card (GForce or Radeon);
* use lastest safe video drivers;
* use DirectX 8.1 (if you are using Java3D D3D) ;
* Use spheres with enough (not excessive) number of faces;
* Use corretly the interpolators ( see SphereMotion demo as example);
* Do NOT create new geometries, new vectors3f , new Transform3Ds each
frame. Just set the new values;
* Use behavior with wakeup with WakeupOnElapsedFrames each 0 or 1 frame
elapsed. Use a field to store this WakeUpOnElapsedFrames object,
avoiding create another one each frame;

I hope it helps you.

Hi, I am having some serious performance problems with my 3D
visualisation system. How can I improve performance and reduce
flickering, the code is quite long so I wont show it here, but
basically the scene renders some spheres and then re-draws them every
few milliseconds in slightly different locations, the idea being that
the movement of the spheres appears smooth, but it doesn t.

Any help would be much appreciated, I can show the code if anyone
feels like offering specific help:)

PS please don t point me to Sun s performance tuning guide, I ve been
through it a number of times.

Thanks in advance
