DreamFusionAcc

Overview

This is a minimal PyTorch implementation of DreamFusion and its variant Magic3D, where we utilize Instant-NGP as the neural renderer and Stable Diffusion/DeepFloyd IF as the guidance.

It takes ~30min to train with Stable Diffusion and ~40min with DeepFloyd IF on a single 3090.

⚠️ This repo has not yet been well-optimized, e.g., memory usage and lack of refinement stage. However, it is still a good reference for its easy-to-follow and lightweight implementation. Please use stable-dreamfusion or threestudio for better quality 3D generation and mesh export.

Installation

git clone https://github.com/chinhsuanwu/dreamfusionacc.git
cd dreamfusionacc
pip install -r requirements.txt

Dependencies

• torch
• tinycudann
• nerfacc
• numpy
• imageio
• einops
• diffusers
• trainsformers

You may install the pre-built wheels for NerfAcc. Please check out here. This repo is built upon torch 1.13.0 + cu117.

Howtos

To train

python train.py --config config/peacock.yaml

You can find all controllable settings in the yaml file. After the training is done, run

python test.py --config config/peacock.yaml

to render 360˚ visualizations.
