GLB to OBJ Conversion

[c0zaut]

Hi! First off, thank you for the amazing work that you all do!

I think I have a pretty close approximation of the Objaverse subset that you used (no animation, faces < 500, only glbs with descriptions,) but am having some issues converting the glb files into obj strings.

I can export the GLB into obj files, but would really appreciate some guidance on how you calculated the vertices so they did not need any texture or normal data, and as signed integers.

It also looks like maybe you capped vertex count, as well. If you did, could you share that limit, too?

Thank you, again!

Thank you for your interest in our work! We use the util functions in the repo of Pivotmesh for quantization of obj files.

THANK YOU!!!!! I will try out some tests later this weekend!

Can you also confirm the the max vertices, if any, of the objaverse dataset? That appears to be the only missing component. Once I have that, I can generate Parquet using pyarrow of the unified data. I plan on using it for static quantization with the Rockchip 3588 NPU SDK, RKLLM: https://github.com/airockchip/rknn-llm/blob/1a502afb52bddc49c2f4e9c0b025b7ab471467a9/rkllm-toolkit/examples/test.py#L28

My current implementation is here: https://github.com/c0zaut/RKLLM-Gradio
