A port of Microsoft's TRELLIS.2 (4B parameter image-to-3D model) to run on Apple Silicon via PyTorch MPS.

Technical Positioning

Enables offline, cloud-independent image-to-3D model generation on Apple Silicon, removing the dependency on Nvidia GPUs and CUDA.

SaaS Insight & Market Implications

This port addresses a significant hardware and ecosystem barrier for developers and designers working with 3D generation. By enabling Microsoft's TRELLIS.2 model to run on Apple Silicon without Nvidia GPUs or CUDA, it democratizes access to advanced image-to-3D capabilities. This reduces infrastructure costs and eliminates cloud dependencies, appealing to users with privacy concerns or limited internet access. While slower than high-end Nvidia GPUs, the offline capability and platform accessibility open new avenues for local development and creative workflows. This trend of optimizing complex AI models for diverse hardware platforms is crucial for broader adoption and innovation in fields like gaming, product design, and virtual reality.

Show HN: TRELLIS.2 image-to-3D running on Mac Silicon – no Nvidia GPU needed

I ported Microsoft's TRELLIS.2 (4B parameter image-to-3D model) to run on Apple Silicon via PyTorch MPS. The original requires CUDA with flash_attn, nvdiffrast, and custom sparse convolution kernels: none of which work on Mac.I replaced the CUDA-specific ops with pure-PyTorch alternatives: a gather-scatter sparse 3D convolution, SDPA attention for sparse transformers, and a Python-based mesh extraction replacing CUDA hashmap operations. Total changes are a few hundred lines across 9 files.Generates ~400K vertex meshes from single photos in about 3.5 minutes on M4 Pro (24GB). Not as fast as H100 (where it takes seconds), but it works offline with no cloud dependency.github.com/shivampkumar/trel...

Well done

Nothing much here. WTF is this near number 1 on the front page of HN?

So much effort, but no examples in the landing page.

Nice work. Although this model is not very good, I tried a lot of different image-to-3d models, the one from meshy.ai is the best, trellis is in the useless tier, really hope there could be some good open source models in this domain.

That’s always been possible with MPS backend, the reason people choose to omit it in HF spaces/demos is that HF doesn’t offer an MPS backend. People would rather have the thing work at best speeds than 10x worse speeds just for compatibility.
