Optimize mesh data

Post  freebird373 on Tue Feb 17, 2009 8:07 pm

After exporting objects from blender, is there a way to optimize the output for triangle strips?
Any ideas of other ways of optimizing the mesh data?
Thanks a bunch. Tim

Triangles strip are not really optimal for mesh... The processing time to create the "perfect" strips is extremely long and not practical, any other "light" approaches will result in multiple VBO that will eventually slow down the rendering due to extra unnecessary binding. SIO2 is using indexed triangles list and index cache optimization (FIFO) which gives the best performance on the device.

Okay thanks.

Guess I'll just minimize the triangle count.
Shooting for 20 fps with 6k tris and physics. Very Happy

Actually with the recent version of SIO2 (1.3.?) I achieve 40+ fps with 15k of triangles + physics... while profiling I realize that the texture switch is more slow than I thought... I suggest you to use texture atlas... check for "Image Consolidator" script within Blender or create the atlas yourself....

Hope this helps,

Cheers,
