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

A developer ported Microsoft's TRELLIS.2 image-to-3D model to run on Apple Silicon using PyTorch MPS, replacing CUDA-specific operations with pure-PyTorch alternatives. The port generates 400K-vertex meshes from single photos in ~3.5 minutes on an M4 Pro (24GB), though slower than H100 GPUs, and eliminates cloud dependency.
