Could someone explain setInitialCoordIndex and setValidVertexCount, etc. I
tried setting the valid vertex count for my by-ref geometry to less than the
total number of vertices in my arrays. But I am taking a performance hit if
for example, I have room for 8,000 vertices in my arrays, but set the valid
vertex count to 400. Seems to me that it is processing them all or
something.
Then there is this setInitialCoordIndex, with no corresponding
setLastCoordIndex. Why use the word "index"? is this only for indexed
geometries? Also, this is only for by-ref geometry? What if I want to
change the number of vertices processed in a non-by-ref geometry array?
Thanks in advance.
