Re: [PyOpenGL-Users] gluNurbsCurve ?

[Prashant S. <ani...@ya...>]

Thanks,

Yes, after explicitly specifying "knot" attribute the curve is drawn properly.
Could you please tell me how to calculate knots using degree and 
number of points?

Your raw code specified a Nurbs curve of order 3 (so polynomial degree 
2, a quadratic curve), and set 5 control points. Since the 'knot' 
attribute was not specified, I assume you relied on the default.

Does the code get the behavior you expect if you explicitly specify a 
"knot" attribute ? ( for example:

knot = [0.0,0.0,0.0, 0.33, 0.67, 1.0, 1.0, 1.0]  # note: length - 8 list

)
