Hi!

I would suggest chunking up your work (assuming that calculating your colour is indeed a significant amount of work) in tiles or something, then fork off a thread for each of them, sticking the final colours in a Chan. Then you have another thread just pick tiles off the Chan and copy the results to the frame buffer.
Is there some completely different and maybe better way of rendering the image? Because I noticed that in fact I do not really have any use for OpenGL (I draw pixels on a 2D plane). So maybe is there some other portable way of rendering a 2D image, which would be easier to parallelize? Maybe of precomputing the image in completely functional way and then only draw the whole image at once to the screen buffer (now I call OpenGL draw pixel function for every pixel I want to draw - this is probably not the best way).
