Class SurfNurb
source code
The SurfNurb Object
This object provides access to the control points of the surfaces
that make up a Blender Curve.
The SurfNurb supports the Python iterator and sequence protocols
which means you can use a python for statement or [] operator to
access the points in a surface. Points are accessed linearly; for a
N-by-M UV surface, the first N control points correspond to V=0, then
second N to V=1, and so on.

|
Set the Nth control point in the surface.
- Parameters:
n (integer) - the index of the point to replacepoint (list of 4 floats (optional 5th float is the tilt value in
radians)) - the point that will replace the one in the curve. The point is
list of 4 floats in x,y,z,w (optionally tilt in radians as 5th
value) format. - Returns: None
- None
|
|
Get the Nth control point in the surface.
- Parameters:
n (integer) - the index of the point to return - Returns: List of 5 floats [x, y, z, w, t] for Poly or Nurbs
- The Nth point in the curve
Notes:
-
This returned value is independent on the curve; modifying it will
not affect the curve.
-
Each successive call returns a new object.

flagU
The knot flag U. Changing the knot type automatically recalculates the
knots. The flag can be one of three values:
-
0 : uniform knots
-
1 : endpoints knots
-
2 : bezier knots
- Type:
- int
|
flagV
The knot flag V. See flagU for description.
- Type:
- int
|
orderU
The order setting for the U direction. Values are clamped to the range
[2:6] and not greater than the U dimension.
- Type:
- int
|
orderV
The order setting for the V direction. Values are clamped to the range
[2:6] and not greater than the V dimension.
- Type:
- int
