LEEWGL

Lightweight-Editor-Environment-Web-GL is a javascript framework which provides an environment for a basic WebGL game engine. It is written using plain javascript with no external dependencies except for glMatrix as math library.

Run

To run LEEWGL locally you need to set-up a webserver [eg. Apache] and open the index.html through the webserver.
