Project Page | Arxiv | Weights | Code

Introduction

3DTopia-XL scales high-quality 3D asset generation using Diffusion Transformer (DiT) built upon an expressive and efficient 3D representation, PrimX. The denoising process takes 5 seconds to generate a 3D PBR asset from text/image input which is ready for the graphics pipeline to use.

Model Details

The model is trained on a ~256K subset of Objaverse. For more details, please refer to our paper.
