🚀 MeshAnything: Artist-Created Mesh Generation with Autoregressive Transformers

MeshAnything is a project focused on mesh generation using autoregressive transformers. It provides various methods for mesh and point cloud inference, enabling users to generate meshes from different types of inputs.

🚀 Quick Start

Installation

Our environment has been tested on Ubuntu 22, CUDA 11.8 with A100, A800 and A6000.

git clone https://github.com/buaacyw/MeshAnything.git && cd MeshAnything
conda create -n MeshAnything python==3.10.13
conda activate MeshAnything
pip install torch==2.1.1 torchvision==0.16.1 torchaudio==2.1.1 --index-url https://download.pytorch.org/whl/cu118
pip install -r requirements.txt
pip install flash-attn --no-build-isolation

Usage

Local Gradio Demo

python app.py

Mesh Command line inference

# folder input
python main.py --input_dir examples --out_dir mesh_output --input_type mesh

# single file input
python main.py --input_path examples/wand.ply --out_dir mesh_output --input_type mesh

# Preprocess with Marching Cubes first
python main.py --input_dir examples --out_dir mesh_output --input_type mesh --mc

Point Cloud Command line inference

# Note: if you want to use your own point cloud, please make sure the normal is included.
# The file format should be a .npy file with shape (N, 6), where N is the number of points. The first 3 columns are the coordinates, and the last 3 columns are the normal.

# inference for folder
python main.py --input_dir pc_examples --out_dir pc_output --input_type pc_normal

# inference for single file
python main.py --input_dir pc_examples/mouse.npy --out_dir pc_output --input_type pc_normal

✨ Features

• Mesh Generation: Generate meshes from images using autoregressive transformers.
• Multiple Input Types: Support both mesh and point cloud inputs.
• Command Line Inference: Provide command line interfaces for easy inference.

Important Notes

• It takes about 7GB and 30s to generate a mesh on an A6000 GPU.
• The input mesh will be normalized to a unit bounding box. The up vector of the input mesh should be +Y for better results.
• Limited by computational resources, MeshAnything is trained on meshes with fewer than 800 faces and cannot generate meshes with more than 800 faces. The shape of the input mesh should be sharp enough; otherwise, it will be challenging to represent it with only 800 faces. Thus, feed-forward image-to-3D methods may often produce bad results due to insufficient shape quality. We suggest using results from 3D reconstruction, scanning and sds-based method (like DreamCraft3D) as the input of MeshAnything.
