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
