MeshoptCompression with quantize

[long-duc-nguyen-skymavis]

In the quantize documentation, it is stated that:

When applying meshopt compression with EXTMeshoptCompression, quantization is usually applied before compression.

However, in the EXTMeshoptCompression example, quantize() is applied after mesh compression.

await document.transform(
    reorder({encoder: MeshoptEncoder}),
    quantize()
);

Should I perform quantize() before or after mesh compression?

Hi @long-duc-nguyen-skymavis — the reorder() function is not the compression, it's only sorting the vertices to improve compression and performance later. The reorder() and quantize() functions modify the in-memory representation of the scene, compression (whether it's Meshopt or Draco) will be applied only when writing to disk.

I don't expect the order in which reorder() and quantize() are called should matter much, but feel free to try both ways and compare.
