gluNurbsSurface

define the shape of a NURBS surface

Signature

gluNurbsSurface( GLUnurbs* ( nurb ) , GLint ( sKnotCount ) , GLfloat* ( sKnots ) , GLint ( tKnotCount ) , GLfloat* ( tKnots ) , GLint ( sStride ) , GLint ( tStride ) , GLfloat* ( control ) , GLint ( sOrder ) , GLint ( tOrder ) , GLenum ( type ) )-> void
gluNurbsSurface( nurb , )
```Pythonic version of gluNurbsSurface

Calculates knotCount, stride, and order automatically
```

Parameters

VariablesDescription
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 GLU_MAP2_VERTEX_3 or GLU_MAP2_COLOR_4 ).
