At least on android, this is detrimental because this gives more work to the GC, especially during tight rendering loops. This could be rewritten with a fixed 16 or 8 levels (or configurable) stacks. 2064 1 sgothel 2012-12-29 23:51:00 +0100 You are referring to glPushMatrix/glPopMatrix ? If so .. I agree. Do you like to make that [git] patch ? 2070 2 sgothel 2012-12-31 15:10:25 +0100 http://jogamp.org/git/?p=jogl.git;a=commit;h=96f8f55a8db5f430fc17ce9ea1bf45e4728ab6ac Enhance PMVMatrix: Use FloatStack to implement PushMatrix and PopMatrix (Bug 657) One FloatStack for each, MV, P and T, with initialialSize zero to save memore and growSizes: MV = 16 arrays, P = 2 arrays, T = 2 arrays, with array = 16 floats. This shall save performance due to the preallocated stack when used and growing only in the above mentioned grow intervals. We may finetune the growSize, if required.
