how to encode mesh in c++

[lihongyi1234]

I'm confused wirh encode .obj file when I look at demo code, where i can set compress params

What parameters are you asking about?

use N-bit uqntization for position/texture/normal parameters that encode in draco

Ah - that's a quantization step that is really up to the application to design/implement. The demo program implements two simple variants, see two packMesh functions in the source, but really it somewhat depends on the requirements - and some implementations may require additional shader decoding (e.g. the second packMesh variant uses an octahedral normal encoding that's optimal from the compression & quality perspective but requires a couple shader instructions to undo).
