About PyOpenGL
I follow the , write a small test:
#!/usr/bin/env python
# encoding=utf-8
import sys
from OpenGL.GL import *
from OpenGL.GLUT import *
def display():
glClear(GL_COLOR_BUFFER_BIT)
glColor(1.0, 1.0, 1.0)
glBegin(GL_POLYGON)
glVertex(0.25, 0.25, 0.0)
glVertex(0.75, 0.25, 0.0)
glVertex(0.75, 0.75, 0.0)
glVertex(0.25, 0.75, 0.0)
glEnd()
glFlush()
def init():
glClearColor(0.0, 0.0, 0.0, 0.0)
glMatrixMode(GL_PROJECTION)
glLoadIdentity()
glOrtho(0.0, 1.0, 0.0, 1.0, -1.0, 1.0)
def main():
glutInit(sys.argv)
glutInitDisplayMode(GLUT_SINGLE|GLUT_RGB)
glutInitWindowSize(250, 250)
glutInitWindowPosition(100, 100)
glutCreateWindow('hello')
init()
glutDisplayFunc(display)
glutMainLoop()
if __name__ == '__main__':
main()
But I got an error:
Traceback (most recent call last):
File "test.py", line 36, in

File "test.py", line 26, in main
glutInit(sys.argv)
File "c:\python25\lib\site-packages\PyOpenGL-3.0.0b8-py2.5-win32.egg

OpenGL.error.NullFunctionError: Attempt to call an undefined function
__glutInitWithExit, check for bool(__glutInitWithExit) before calling
Can anyone please tell me why?

It works now! Thank you very much! -- http://mail.python.org/mailman/listinfo/python-list
