A ClojureScript sandbox for WebGL.

Create WebGL tutorial examples utilizing cljs-webgl, which binds WebGL to ClojureScript. It (cljs-webl) allows a more convenient functional style for creating WebGL applications in ClojureScript, by means of hiding mutability where possible and wrapping every Javascript value in ClojureScript constructs.

The program below can be run by first building:

$ lein cljsbuild once min

And then opening the resources/public/index.html page in a webGL capable browser.

Alternatively (when you're developing your own examples), Figwheel support has been added for a better, more interactive development experience:

$ lein figwheel

then point your webGL capable browser to http://localhost:3449/index.html

To change to another example (e.g., triangle -> projection -> texture-map), comment out the other examples in src/examples/examples.cljs from lines 3-5. Then, modify lines 24 and 80 with the example you wish to run.

1. triangle.cljs - draw a triangle with a one-to-one mapping from model space to GL clip space
2. projection.cljs - draw a shape by transforming [ModelViewProjectionMatrix] X (Square Vertices). Default is a perspective projection. Choose an orthographic projection by uncommenting line 119 and commenting out line 121. Choose another shape (e.g., triangle, cube) by modifying lines 13, 20, 30 & 36.
3. texture-map.cljs - draw a shape from basic-shapes.cljs using a WebGL logo as a texture map.

• Fork cljs-webgl and port it to WebGL2
• UI support for selecting examples
