Hey all. Foolish me forgot to check the bug parade so I've spent the last day rewriting my particle system to find out why the setValidVertexCount is now only increasing the size of a QuadArray's vertex count, and not decreasing. Seems this is a bug in j3d1.3beta.
Anyhow - I'm wondering on the best way to implement this using TriangleFanArray.. setStripVertexCounts requires me to do a (int[])Array.newInstance(int.class, numParticles) and fill for each addition/removal of a particle (though these are batched so creation/deletion of a large number of particles in a single frame only needs to do this once). I'm thinking that a better way to do this would be to simply have the strip index list constantly as large as the initial max number of verticies / 3 (for worse case scenario). Then a setValidStripCount(int numStrips) would be the equivilent of the setValidVertexCount that non-stripped geometry uses. Setting the number of verticies in a given strip then would be provided with get/setStripVertexCountAtIndex(int index) Or is this too complicated and the array newInstance'ing/filling isn't much of a hit at all? ------------------------ Chris Forrester http://www.geocities.com/Psionic81 _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
