Subject: Re: [9fans] Drawterm GPU (was: Software philosophy)

I should mention I thought about the layout of a GPUfs some time ago. I 
just lack lots of knowledge about this, the gist was to write shader 
(code or compiled?) into some files, also write image data and mesh data 
to other files, abd reading results from other files. But as I said, I 
lack lots of knowledge about how GPUs work and never wrote any OpenGL 
code myself, only shader code. It always seemed like it's hundreds of 
hundreds of lines of code to draw a triangle (which is the basic hello 
world program).
