En3D: An Enhanced Generative Model for Sculpting 3D Humans from 2D Synthetic Data
Yifang Men, Biwen Lei, Yuan Yao, Miaomiao Cui, Zhouhui Lian, Xuansong Xie

En3D is a large 3D human generative model trained on millions of synthetic 2D data, independently of any pre-existing 3D or 2D assets. This repo contains an implementation of En3D and provides a series of applications built upon it. In addition, this repo aims to be a useful creative tool to produce realistic 3D avatars from seeds, text prompts or images, and support automatic character animation FBX production. All outputs are compatible with the modern graphics workflows.

Updates

(2023-01-15) ModelScope and HuggingFace Online demo is available! Try out .

(2023-01-15) A Rigged & Animated 3D Human library (3DHuman-Syn) is released, containing ~1000 avatars produced by En3D for quick experience. Infinite avatars and actions support will be coming soon!

(2023-01-03) The paper and video are released.

Web Demo

• Integrated an online demo into ModelScope. Try out and have fun!

• Integrated an online demo into Huggingface Spaces 🤗. Try out and have fun!

Installation

git clone https://github.com/menyifang/En3D.git
cd En3D
conda create -n en3d python=3.8
conda activate en3d
pip install -r requirements.txt

Quick Start

WebUI usage

[Recommended] A deployed Online Demo

With own machine, you can also deploy our demo as below, which provides flexible user interface. Both CPU/GPU are supported for avatar render and animation, only GPU (>24G memory) is supported for avatar generation.

python app.py

Synthetic avatar library

We released a Rigged & Animated 3D Human library (3DHuman-Syn), containing ~1000 characters produced by En3D, and 1000+ actions are provided for animation.

• Avatar download and rendering

python render.py

• Avatar animation

python animation.py

• AR application

Convert the generated animation file (.glb) to .usdz format using Sketchfab (upload glb and download usdz) or other tools, and insert the animated avatar to web with model-viewer.

<!-- Import the component -->
<script type="module" src="https://ajax.googleapis.com/ajax/libs/model-viewer/3.3.0/model-viewer.min.js"></script>

<!-- Use it like any other HTML element -->
<model-viewer src="assets/human.glb" camera-controls ar shadow-intensity="1" ios-src="assets/human.usdz"></model-viewer>

AR function is only supported with iPhone, try the AR example in the phone browser and click the right-down icon for AR experience.
