Single Pixels

I am in a class on graphics programming and one of our assignments is to draw a picture using nothing but lighting up individual pixels. I know how to do it in Visual C++ but I would really like to do it all in openGL. I can’t find any info on how to do it. Anyone know?

Well if the pixels need to be right next to each other you’ll want to use textures (similar to bitmaps). If you just want points in a space, you could use GL_POINTS.
