Hi, Using OpenGL to draw something that will end up on paper might prove somewhat complicated. As for "translating" a shader to something cpu bound, since a shader is more or less a program in some language that "has some remote parentness with C", you could probably do it. But the most pragmatic way, IMHO, is to understand what the program does and rewrite it. If you really want to leverage OpenGL's power, I know it allows you to render "in memory" so you could draw things on a virtual screen, grab the output, and you're set. To some extent, recent OpenGL with shaders is more or less a generic way to harness the power of massive parallel, dedicated hardware, and it's very versatile. But complex as well.
If you are not a graphics guru, I'd advice you to use a plain simple native Go library, there are several candidates, one is : https://github.com/llgcode/draw2d/ Have a nice day, Christian.
