   Triangle tesselation
  I was looking into triangle tesselation, and while I have managed to successfully create a recursive tesselation routine. im wondering how to get a smooth result. As at the moment I simply tesselate over the triangles plane, so the end result is obviously just as flat looking as the original model.Now i cant seem to find much in regard to triangles. A lot of the stuff im finding is to do with square patches.Does anyone have any related links I could have a look at?   
  Use normals (or normal map) to shape the model? Or some sort of height map extruded along the normals?   ;Quote:Original post by maya18222I was looking into triangle tesselation, and while I have managed to successfully create a recursive tesselation routine. im wondering how to get a smooth result.

Searching for tutorials or sample implementations might help you. I don´t know if it works with triangles, but you can subdivide and then triangulate afterwards.   ;  @NecroDOME Im looking for actual subdivision techniques@ArKano22 Thanks, I'll look into that.   ;  Here are some more links having to do with triangulation:http://www.vterrain.org/Implementation/Libs/triangulate.htmlBut as ArKano22 mentioned, I think you're interested in model/polygon/triangle subdivision.;  Yep thanks. Its not the trianglulation im having trouble with though. Its the smoothing being done at the same time. ie But i think ArKano22's suggestion is relevent to what I need
