Re: [pygame] Using PyOpenGL for 2D graphics

[Matthew Marshall <matthew@xxxxxxxxxxxxxxxxxxx>]

I'll also throw in a mention of my own project, Rabbyt 
(http://matthewmarshall.org/projects/rabbyt/)  Like Simon's GFX, it's done in 
Pyrex for speed.  (The two libraries can actually be used simultaneously 
without problems.)

Here's a port of Simon's "dumb" example (quick, untested):

import pygame
import rabbyt

rabbyt.init_display()

ball = rabbyt.Sprite("ball.png")

# Make the ball bounce up and down :-)
ball.y = rabbyt.lerp(0, 100, dt=1000, extend="reverse")

running = True
while running:
    if QUIT in (i.type for i in pygame.event.get()):
        running = False
    rabbyt.clear()
    rabbyt.set_time(pygame.time.get_ticks())
    ball.render()
    pygame.display.flip()
