Howdy folks, I have ported a wonderful simplification algorithm written in c to babylonJS. It is based on http://www.cs.cmu.edu/afs/cs.cmu.edu/user/garland/www/Papers/quadric2.pdf and http://voxels.blogspot.de/2014/05/quadric-mesh-simplification-with-source.html . What can you do with it? It can be used to automatically create LOD objects for meshes (if the user has time for that) directly in the browser. It is surprisingly fast - it is reducing ca. 130000 triangles to 65000 in less than 5 seconds on my good ol' laptop. Example can be seen here - http://babylonjsexperiments.raananweber.com/?rate=0.5 , the fractal object (generated using meshlab) contains ca. 131000 triangles. Wait a few seconds for it to load and decimate. The object on the right is the original, on the left is the reduced. The rate can be change in the URL. At 0.3 it is still relativly hard to find the difference. At 0.1 it is very clear. But this is exactly what's needed for LOD. At the moment I am not analyzing the UVs (meshlab doesn't generate them as well), this would be the next step. Making it Async is also on the todo list :-) Edit - Preview site changed, check my following post about the new async implementation.
