from screen import *

image = Image(640,480)

image.pixel(100, 150, (255,0,0))
image.pixel(200, 250, (0,255,0))
image.pixel(250, 100, (0,0,255))

image.show()
image.save("out.png")

Graphics demo programs

Also included is a few samples of very primitive graphics code, to demonstrate how such things function under-the-hood. Do note that these are all written for teaching purposes, and only "trivial" optimizations are taken where they do not sully the learning experience.

triangle.py - demos how triangles are rasterized to the screen. raytracer.py - a very simple raytracer, complete with camera and materials and all.
