Derived from the websperience hypVR-Ray by Roice Nelson, Henry Segerman and Michael Woodard featured over at https://github.com/mtwoodard/hypVR-Ray, which was in turn based on the websperience by Vi Hart, Andrea Hawksley, Sabetta Matsumoto and Henry Segerman featured over at https://github.com/hawksley/hypVR.

Running Locally

Running this locally requires a simple web server (to source the shader files at runtime), with the root at the same level as index.html. This can be done in python 3 by running the command "python -m http.server". In python 2, run the command "python -m SimpleHTTPServer 8000", then go to "http://localhost:8000/" in your browser. On Windows, you can set up a server in the Control Panel Administrative Tools, in the IIS Manager (you may need to turn this feature on first). NOTE: The server will need to have a MIME type configuration for .glsl files set to "text/plain".
