Decompression Performace Improvement

Open liaocheng opened this issue 4 years ago • 2 comments

I made a benchmark on PC platform. It turns out that the draco decompression time is closed to lzma on the same mesh. Is it possition to improve the decompression through SIMD or any other method?

image Here is the benchmark result. Draco's compress ratio is very high. It would be great if the decompress performance cound be improved.

SIMD could potentially help decoding performance. Best potential optimizations would probably be normals or texture coordinates.

We don't have any plans to try and optimize the decoder using SIMD.
