This Django project, based on ROMP, WebSocket, Channels, WebRTC and Three.js, does two things:
- Use a webcam to drive a single 3D character in real time in a web page.
- Multiple people join the same chatroom, communicating with each other and seeing the 3D characters of themselves and others. Each part supports multiple 3D characters driven by multiple people.
The principle of the project can be find in the following paper: WOC: A Handy Webcam-based 3D Online Chatroom
Go to webcam module to have a fast try. You can drive a 3D character with your webcam.
Go to Characters module. Then you can chooese your favourite 3D character and start chatting with others as shown below.
In this module, you can chat with others using your 3D characters. (Your video will not transmit to others. The images and videos are just for the sake of showing the effect.)

First, enable SSL in the nginx configuration file.
# /etc/nginx/nginx.conf
server {
listen 443 ssl;
server_name www.your_domain_name.com your_domain_name.com;
ssl_certificate /path/to/your/cert
ssl_certificate_key /path/to/your/key
ssl_session_timeout 5m;
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

}Second, run the coturn server to enable the WebRTC connection.
sudo apt install coturn
sudo vi /etc/turnserver.conf
sudo systemctl start coturn# /etc/turnserver.conf
