OpenGL and TrimCurves

Am I correct to understand that not all trim curves are to be treated as gluNurbsCurve, some of them should be treated as gluPwlCurve ?

If so, how do I determine that within OpenNURBS so that I may prepare the data accordingly for OpenGL ?


Hi @Nicholas_Yue,

I don’t now anything about gluPwlCurve - sorry.
