gluNurbsCurve
Chapter 12
306
When gluNurbsCurve appears between a gluBeginTrim/gluEndTrim pair, it is used to
describe a trimming curve on a NURBS surface. If type is GLU_MAP1_TRIM_2, then it
describes a curve in two-dimensional (u and v) parameter space. If it is
GLU_MAP1_TRIM_3, then it describes a curve in two-dimensional homogeneous (u, v,
and w) parameter space. See the gluBeginTrim reference page for more discussion about
trimming curves.
Notes
To define trim curves that stitch well, use gluPwlCurve.
