Variables  Description 

target 
Specifies the kind of values that are generated by the evaluator.
Symbolic constants
GL_MAP2_VERTEX_3
,
GL_MAP2_VERTEX_4
,
GL_MAP2_INDEX
,
GL_MAP2_COLOR_4
,
GL_MAP2_NORMAL
,
GL_MAP2_TEXTURE_COORD_1
,
GL_MAP2_TEXTURE_COORD_2
,
GL_MAP2_TEXTURE_COORD_3
, and
GL_MAP2_TEXTURE_COORD_4
are accepted.

u1, u2 
Specify a linear mapping of
$\mathit{u}$
,
as presented to
glEvalCoord2
,
to
$\stackrel{}{\mathit{u}}$
,
one of the two variables that are evaluated by the equations specified
by this command. Initially,
u1
is 0 and
u2
is 1.

ustride 
Specifies the number of floats or doubles between
the beginning of control point
${\mathit{R}}_{\mathit{ij}}$
and the beginning of control point
${\mathit{R}}_{\left(\mathit{i}+1\right)\mathit{j}}$
,
where
$\mathit{i}$
and
$\mathit{j}$
are the
$\mathit{u}$
and
$\mathit{v}$
control point indices, respectively.
This allows control points to be embedded in arbitrary data structures.
The only constraint is that the values for a particular control point
must occupy contiguous memory locations. The initial value of
ustride
is 0.

uorder 
Specifies the dimension of the control point array in the
$\mathit{u}$
axis.
Must be positive. The initial value is 1.

v1, v2 
Specify a linear mapping of
$\mathit{v}$
,
as presented to
glEvalCoord2
,
to
$\stackrel{}{\mathit{v}}$
,
one of the two variables that are evaluated by the equations specified
by this command. Initially,
v1
is 0 and
v2
is 1.

vstride 
Specifies the number of floats or doubles between
the beginning of control point
${\mathit{R}}_{\mathit{ij}}$
and the beginning of control point
${\mathit{R}}_{\mathit{i}\left(\mathit{j}+1\right)}$
,
where
$\mathit{i}$
and
$\mathit{j}$
are the
$\mathit{u}$
and
$\mathit{v}$
control point indices, respectively.
This allows control points to be embedded in arbitrary data structures.
The only constraint is that the values for a particular control point
must occupy contiguous memory locations. The initial value of
vstride
is 0.

vorder 
Specifies the dimension of the control point array in the
$\mathit{v}$
axis.
Must be positive. The initial value is 1.

points 
Specifies a pointer to the array of control points.
