首先还是下载PyOpenGL包:http://pypi.python.org/pypi/PyOpenGL/3.0.2

在Windows下,安装还是很简单的,安装程序会主动找到你的python目录,所以可以直接下一步。

安装好了后，就来写一个脚本测试一下~

test.py

from OpenGL.GL import *

from OpenGL.GLU import *

from OpenGL.GLUT import *

def Draw():

glClear(GL_COLOR_BUFFER_BIT)

glRotatef(0.5, 0, 1, 0)

glutWireTeapot(0.5)

glFlush()

glutInit()

glutInitDisplayMode(GLUT_SINGLE | GLUT_RGBA)

glutInitWindowSize(400, 400)

glutCreateWindow("test")

glutDisplayFunc(Draw)

glutIdleFunc(Draw)

glutMainLoop()

可以看到，在python中同样可以使用glut来创建窗口，语法遵从Python，但是大体上的结构还是和c语言的glut库差不多。

下面为一个时钟的例子

from OpenGL.GL import *

from OpenGL.GLU import *

from OpenGL.GLUT import *

import math

import  time

h=0

m=0

s=0

glEnd()

glLineWidth(2)

for i in range(100):

glEnd()

glEnd()

glBegin(GL_POLYGON)

for i in range(100):

glVertex2f(0.03*math.cos(2*PI/100*i),0.03*math.sin(2*PI/100*i));

glEnd()

glFlush()

def Update():

global h,m,s
