Reduce_polygons main function to reduce the mesh On the other hand, every error is computed twice - but that's not so serious.Ĭalculate_error calculates the error between two vertices and output the vertex an edge might be reduced to. This avoids the edges list completely as the edge list is slow creating and updating. (Single threaded) by using less memory than most other methods.Īlgorithm Different from the original method, it does not store the per-edge-error in an edges list, but per triangle. Its able to reduce 90% of 650.000 triangles in about 1 sec. #MESHLAB SIMPLIFY MESH FOR FREE#In turn, everyone gets a great mesh simplification method for free once it works If one of you can spot it, any help is appreciated. I searched already a while but couldnt find it yet. ![]() ![]() Its quite short (130 lines for the main part), but apparently there is a bug somewhere. Summary I am currently on a new implementation of a Quadric based mesh simplification algorithm. ![]()
