Creating an Interpolated Surface

A new interpolated NURBS surface can be created with the Create Interpolated Surface command.

To create an interpolated surface:

1. Select Model > 3D Power Pack > Create Interpolated Surface.

2. Click to define the start of the interpolation point row, and then click again to define the end of the row. Click a third time to define the column of interpolation points.

 

The Create Interpolated Surface dialog box opens.

3. Specify the number of interpolation points and degree of flexibility to create for both the U and V direction.

Click to show/hide the parameters.

Parameter	Description
U Direction
Number of Points	Specifies the number of interpolation points (up to 1000) to create in the U direction; this number must be greater than the U degree number
Degree	Indicates the flexibility of the surface in the U direction, from 1 to 28; a larger number results in a more variable surface
V Direction
Number of Points	Specifies the number of interpolation points (up to 1000) to create in the V direction; this number must be greater than the V degree number
Degree	Indicates the flexibility of the surface in the V direction, from 1 to 28; a larger number results in a more variable surface

4. Click OK to create the interpolated surface. Select Show Vertices from the Object Info palette to display the interpolation points. Use the Reshape tool to reshape the interpolated NURBS surface.
