  Abstract: *A diffusion model learns to predict a vector field of gradients. We propose to apply chain rule on the learned gradients, and back-propagate the score of a diffusion model through the Jacobian of a differentiable renderer, which we instantiate to be a voxel radiance field. This setup aggregates 2D scores at multiple camera viewpoints into a 3D score, and repurposes a pretrained 2D model for 3D data generation. We identify a technical challenge of distribution mismatch that arises in this application, and propose a novel estimation mechanism to resolve it. We run our algorithm on several off-the-shelf diffusion image generative models, including the recently released Stable Diffusion trained on the large-scale LAION dataset.*

  # Score Jacobian Chaining: Lifting Pretrained 2D Diffusion Models for 3D Generation
  
  This repository provides the official implementation for Score Jacobian Chaining (SJC), a method that repurposes pretrained 2D diffusion models for high-quality 3D object generation.
