Sim Web Visualizer

Web-Based Visualizer for Simulation Environments.

IsaacGym Simulator
SAPIEN Simulator
Static URDF File

This repository hosts a browser-based 3D viewer for physical simulators. It offers users the ability to observe simulations directly within their web browser, as an alternative to the default visualizer that comes with the simulator.

The main feature of this repo is that you only need to modify a server lines of your code to port the visualization on the default simulator viewer to the web visualizer. This feature is especially useful for visualizing simulation on a headless server. For example, train and visualize the IsaacGym tasks inside jupyter notebook on a remote server.

Installation

From pip:

pip install sim_web_visualizer

From source:

Note: this visualizer does not have a Python version requirement but IsaacGym requires Python 3.6, 3.7, or 3.8

git clone https://github.com/NVlabs/sim-web-visualizer
cd sim-web-visualizer && git submodule update --init --recursive
pip install -e .

Troubleshooting: Try to install ZeroMQ libraries on your system if you encounter any related errors.

apt install libzmq3-dev # For ubuntu
brew install zmq # For Mac

Troubleshooting

Can "Upgrade" only to "WebSocket"

This issue may arise if you have entered an incorrect URL into your browser. Ensure that the URL is in the format http://YOUR_IP_ADDRESS:YOUR_PORT_NUM/static/. The /static/ part of the URL is essential and should not be omitted.

404: Not Found

Similar to the previous issue, the correct URL suffix should be /static/, and not /static. The trailing / is mandatory and should not be omitted.
