[PyOpenGL-Users] gluNurbsCurve error 100253

[<2l...@2l...>]

Hi, I'm trying to port one of mine program from Python 2.1 to Python 2.2

I use PyOpenGL-2.0.0.44 binary for Windows with a Nvidia TNT2 opengl driv=
er.

Everythings works well with Python2.1 on an other machine.

I use this function

gluNurbsCurve(nurb, crv.uknots, crv.cntrl, GL_MAP1_VERTEX_4)

where

crv.uknots=3D [ 0.   0.   0.   0.2  0.4  0.6  0.8  1.   1.   1. ]
crv.cntlr=3D
[[-5.   2.5  0.   1. ]
  [-7.5  5.   0.   1. ]
  [ 2.5  5.   0.   1. ]
  [ 0.   0.   0.   1. ]
  [-2.5 -5.   0.   1. ]
  [ 7.5 -5.   0.   1. ]
  [ 5.   2.5  0.   1. ]]

And that what i obtain :

Traceback (most recent call last):
   File "GLCrv.py", line 99, in ?
     main()
   File "GLCrv.py", line 88, in main
     gluNurbsCurve(nurb, crv.uknots, Numeric.transpose(crv.cntrl),=20
GL_MAP1_VERTEX
_4)
OpenGL.GLU.GLUerror: [Errno 100253] l'=DAtendue du n=A3ud valide est vide


I've already passed a couple of day on this problem which drive me crazy.

Thanks for any help.
