 int lruCacheSize)

Optimize faces.

Parameters:

indexList - input index list

indexCount - the number of indices in the list

vertexCount - the largest index value in indexList

newIndexList - preallocated buffer the same size as indexList to hold the optimized index list

lruCacheSize - the size of the simulated post-transform cache (max:64)
