Re: [JAVA3D] Particle System Shape3D and Alpha Blending

Shawn:   I love you guys!   *raises beer to Shawn*   Now, I am a little confused, how can a particle system be implemented in a single triangle strip array since triangles need to be contiguous.... or are you using strips of one or two triangles each?  And are you transforming every vertex yourself on each frame?  Love to know, even in a general sense what you guys are doing.   Dave Yazel Cosm Development Team ----- Original Message ----- From: Shawn Kendall To: [EMAIL PROTECTED] Sent: Monday, October 23, 2000 6:41 PM Subject: Re: [JAVA3D] Particle System Shape3D and Alpha Blending This is fixed in the 1.2.1 beta. Sorry for the noise everyone... :-) Shawn Kendall wrote: Ok, I'm sure many people have had this problem. Our first pass at a "particle system" had this but it was not important for us to fix until now. Our particle group is actually one single Shape3D using a TriangleStripArray.  It runs very fast :-)  Much faster than individual Shape3D with each their own TransformGroup and BillBoard behavior, of course.  In fact, we are finding very near native OpenGL particle systems performance. The problem is alpha blending In the attached picture you can see the alpha blending problem.  Some alpha polys complete overwrite others without blending. I've tried everything I can think of,  short of actually z-sorting the polys.  I'm sure z-sorting is not necessary, because I really to want just a complete blend for just this one Shape3D. Is this one of the unknown alpha bugs or is there something I can set or do to help fix this.
