In October I did my first engine with Ogre4j, then tell me about of SSAO and I immediately said I wanted in my engine. Do not know where I was entering when i say to me these words.
I started trying it with Ogre4j but I had difficult to access to shaders programs with ogre4j.
A month ago I read about WebGL and saw open sky for create my SSAO.
Although i had little idea of OpenGL and Shading Language and i couldnīt see any example with a demo of webgl with ssao, thanks to http://learningwebgl.com and others now I understand how OpenGL work and I'm creating a Framework.
The best is that finally I have created my own custom SSAO (with double pass ). there is a demo here http://www.stormcolor.com/stormEngineC.
The Framework StormEngineC I have it in development and is uploaded at http://code.google.com/p/stormenginec
