Gloss

Gloss hides the pain of drawing simple vector graphics behind a nice data type and a few display functions. Gloss uses OpenGL and GLUT under the hood, but you won't have to worry about any of that. Get something cool on the screen in under 10 minutes.

Gloss is a fork and cleanup of ANUPlot, which has been used for teaching first year computer science at the ​ANU for the last few years. Its main goal is to allow total beginners to get something working with a minimum of fuss.
