How to speed up mesh decimation #44

Open Mikhail2017 opened 6 years ago

Mikhail2017 commented 6 years ago

I'm trying to simplify 120k triangle mesh to 9k with code in tridecimator.cpp sample. Approximately at 70k triangles it runs very slow, so it will take maybe some hours to obtain result. Have compiled with Intel c++ 17.0 & O3 & openMP support & ocf types. Windows 10. Meshlab returns result approximately in 10 seconds. Whats wrong?

Did you figure out how to solve it?

I meet the same problem, can anybody solve it?

Use qparams.QualityQuadric = true kind of accelerated the progress, but still much slower than that in MeshLab.
