There is a strange thing going on with number of triangles. I have a 3ds
model. When viewed inside openfx it has 6236 triangles. When loaded
inside j3dfly it has 12472 triangles. 3ds loader seems to double number
of triangles - probably because of two sided material. So question
number one - What is a two sided material and why it has to be
duplicated, instead of just set to CULL_NONE ?
But what really bugs me is what happens if I try to stripify the
geometry. After stripification number of triangles increasted to 20813.
Why ?
And back to talk about GeometryInfo stripifier. After stripification
average strip length is 4.118052. I hardly see it as a good result. If
it is true that stripifier increased number of triangles to ease it's
work, we would have about 2 triangles per strip in original model... I
hope that just stat display is wrong - in other case we will have almost
2 times triangle count increase with amount of strips being equal to
half of number of original triangles (after doubling by loader). Two
triangle strips hardly look like a performance gain for me.
