What is TRELLIS?

TRELLIS uses a novel 'structured latent' representation — joint sparse-voxel + feature-grid — to generate high-quality 3D assets (mesh + Gaussian splat + radiance field) from images or text. MIT license, image-to-3D and text-to-3D pipelines.

Pros & cons

✓ PROS

  • Outputs mesh + Gaussian splat + radiance field in one shot
  • MIT licensed
  • Microsoft Research backing — solid engineering

– CONS

  • Heavier than Hunyuan3D-2 at equivalent quality
  • Texture quality below dedicated PBR pipelines

What's actually free?
