Signature
Parameters
Variables  Description 

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 singleprecision floatingpoint values)
between successive control points in the parametric
u
direction
in
control
.

tStride 
Specifies the offset (in singleprecision floatingpoint values)
between successive control points in the parametric
v
direction
in
control
.

control  
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
twodimensional evaluator types (such as
GLU_MAP2_VERTEX_3
or
GLU_MAP2_COLOR_4
).
