WebGL hacks « Code Laboratorium

That’s it, I finally found something fun in web development! I never thought I’d live to see the day when I would feel the motivation to learn javascript, but here we are. WebGL is fun, because you can do all the things you could with regular OpenGL, but now you can send URLs to all your friends to show off. I can’t say I liked javascript really, but I guess it’s passable as long as you can avoid the horrible conventions people have established for pretending to write object-oriented code with it.

So what I did, after experimenting to see how WebGL and javascript programming works, is a port of a GPU-raytracer for 4D quaternion Julia fractals, and a simple 360-panorama viewer. You can find those on my webgl hacks page I put up yesterday.

About WebGL itself now, I’m really disappointed they chose to base it on OpenGL ES 2.0, which is the bastard child of a slashed down OpenGL subset initially spec’ed for fixed point embedded devices, and Khronos’ OpenGL >= 3 d3d10-buttlicking madness. I understand why they chose that, because they intend to have WebGL easily implementable on mobile phones and tablets, but I’m still disappointed.

For those of you not well versed in the differences between the various OpenGL versions that suddenly crept up when Khronos group took control of OpenGL and apparently surrendered it over to inmates of the nearest insane asylum, I’ll give you a short overview of what sucks in OpenGL >= 3.x, OpenGL ES 2.0, and WebGL:

So anyway, while I was playing around with it these past few days, I had to bring back a little bit of sanity to WebGL. For that reason I wrote SaneGL , a small piece of code that implements immediate mode drawing, and the OpenGL matrix stack on top of WebGL. I bundled that along with a small matrix math library and some helper functions for WebGL programs in a project called webgl-tools, which you can find in my mercurial repository: https://nuclear.mutantstargoat.com/hg/webgl-tools .
