Description:
|
The routine returns one of the following values:
|
|
|
-2
|
= Curve is a point or a degenerate spline.
|
|
-1
|
= Curve is a straight line,
normal not set.
|
|
0
|
= Curve is nonplanar.
|
|
1
|
= Curve is planar, and
normal is set.
|
|
|
If the given curve is planar, it sets the argument
normal to be the normal of the plane in which the given spline lies.
