w'sKnotCount 'u nurb
Specifies the NURBS object (created with gluNewNurbsRenderer).
sKnotCount
Specifies the number of knots in the parametric u direction.
sKnots
Specifies an array of sKnotCount nondecreasing knot values in the parametric u direction.
tKnotCount
Specifies the number of knots in the parametric v direction.
tKnots
Specifies an array of tKnotCount nondecreasing knot values in the parametric v direction.
sStride
Specifies the offset (as a number of single-precision floating point values) between successive control points in the parametric u direction in control.
tStride
Specifies the offset (in single-precision floating-point values) between successive control points in the parametric v direction in control.
control
Specifies an array containing control points for the NURBS surface. The offsets between successive control points in the parametric u and v directions are given by sStride and tStride.
sOrder
Specifies the order of the NURBS surface in the parametric u direction. The order is one more than the degree, hence a surface that is cubic in u has a u order of 4.
tOrder
Specifies the order of the NURBS surface in the parametric v direction. The order is one more than the degree, hence a surface that is cubic in v has a v order of 4.
type
Specifies type of the surface. type can be any of the valid two-dimensional evaluator types (such as GL_MAP2_VERTEX_3 or GL_MAP2_COLOR_4).
