WebGL is shader based. In my shaders I can write code like
int a = 1;
int b = 2;
int c = a + b;
Is there a way to extract the value of c from shader-land to JavaScript-land?
The output of a WebGL drawing pass is writes to the render target color buffer. You will need to study up on GPGPU programming with OpenGL and WebGL specifically. See this blog post for a discussion on doing GPGPU with WebGL:
