Code

# Import necessary libraries
import pygame
from pygame.locals import *
from OpenGL.GL import *
from OpenGL.GLU import *

# Initialize Pygame
pygame.init()
display = (800,600)
pygame.display.set_mode(display, DOUBLEBUF|OPENGL)

# Set up perspective for 3D rendering
gluPerspective(45, (display[0]/display[1]), 0.1, 50.0)
glTranslatef(0.0,0.0,-5) # Move scene back by -5 units

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()

    glRotatef(1, 3, 1, 1) # Rotate the object

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT)

    glBegin(GL_TRIANGLES)
    glVertex3fv((0,1,-5))
    glVertex3fv((-1,-1,-5))
    glVertex3fv((1,-1,-5))
    glEnd()

    pygame.display.flip()
