I asked Patrick Cozzi if he knew of any WebGL editors working in the browser. There turn out to be quite a few, each with their own focus:
- http://webglplayground.net/ – on the left is the code, on the right is the result. See the gallery for more examples, which tend towards 2D and artistic examples.
- http://glsl.heroku.com/ – code actually overlays the display itself. Here is a more 3D example.
- http://spidergl.org/meshade/index.html – more elaborate, shows separate shaders, model loading, and JSON and HTML generated. To run, click “Load” to load the given model, which you can interact with.
- http://www.shadertoy.com – allows playing with the pixel shader, essentially. Mostly about image deformations, often encountered in old Demo Scene programs.
- http://www.kickjs.org/example/shader_editor/shader_editor.html – for playing with a 3D object and trying out experiments with the vertex and pixel shaders in the GPU.
- http://cesium.agi.com/Cesium/Apps/Sandcastle/index.html – give it time to load (hey, it’s loading the whole world). It shows a quite elaborate development environment. They are using CodeMirror to do the in-browser editor. See their other demos here.
Enjoy! And let us know of any others you find.
