Hello. I am a relatively new python programmer, but I know my way around the language. I have decided to do some work with PyOpenGL -- I just finished a game that had to be in XNA, now I have a bit more free reign and I prefer to do my work with free software, for the obvious reasons.
However, I have had some difficulty with PyOpenGL so far. I have a very very simple test program to make sure that everything is installed. I think that the errors I am getting are trying to tell me that GLUT is not properly installed. What is going on?
from OpenGL.GLUT import *
from OpenGL.GLU import *
from OpenGL.GL import *
import sys
name = 'ball_glut'
def main():
glutInit(sys.argv)
glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH)
glutInitWindowSize(400,400)
glutCreateWindow(name)
glClearColor(0.,0.,0.,1.)
glShadeModel(GL_SMOOTH)
glEnable(GL_CULL_FACE)
glEnable(GL_DEPTH_TEST)
glEnable(GL_LIGHTING)
lightZeroPosition = [10.,4.,10.,1.]
lightZeroColor = [0.8,1.0,0.8,1.0] #green tinged
glLightfv(GL_LIGHT0, GL_POSITION, lightZeroPosition)
glLightfv(GL_LIGHT0, GL_DIFFUSE, lightZeroColor)
glLightf(GL_LIGHT0, GL_CONSTANT_ATTENUATION, 0.1)
glLightf(GL_LIGHT0, GL_LINEAR_ATTENUATION, 0.05)
glEnable(GL_LIGHT0)
glutDisplayFunc(display)
glMatrixMode(GL_PROJECTION)
gluPerspective(40.,1.,1.,40.)
glMatrixMode(GL_MODELVIEW)
gluLookAt(0,0,10,
0,0,0,
0,1,0)
glPushMatrix()
glutMainLoop()
return
def display():
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT)
glPushMatrix()
color = [1.0,0.,0.,1.]
glMaterialfv(GL_FRONT,GL_DIFFUSE,color)
glutSolidSphere(2,20,20)
glPopMatrix()
glutSwapBuffers()
return
if __name__ == '__main__': main()
leads to error:
Traceback (most recent call last):
File "C:/Python25/Py3D/test.py", line 47, in <module>
if __name__ == '__main__': main()
File "C:/Python25/Py3D/test.py", line 10, in main

self.__name__, self.__name__,
NullFunctionError: Attempt to call an undefined function glutInitDisplayMode, check for bool(glutInitDisplayMode) before calling
Is this GLUT difficulties? If so, how do I get GLUT working? Please help. Thank you!
