been there than that :-) The algorithm we use is a (super) optimized version of the octtree algorithm. Notice this sentence in the documents pointed out in the blog post: "The quantizer is fairly slow compared to median cut or octree methods". NeuQuant gives good quality but if you want to use it in place like we do (the guy is doing offline preprocessing) ou'd give up a lot in terms of speed.
I should still have around the speed tests I had made with the various algorithms, I could put them somewhere (I have a blog as well! :-) ). Anyway, there are others novel algorithms that we could try and implement but I wonder if ATM it is worth the effort, I think there are many other things that we could optimize with a similar effort. Mmmmmmhhh, probably topic for an intern. Simone. ------------------------------------------------------- Eng. Simone Giannecchini GeoSolutions S.A.S.
