## 3.31. curveInterpolation command

Description: This option allows the user to draw a curve that goes through a set of points by applying polynomial interpolation.

Inline mode usage:

• curveInterpolation -h: Displays the help file that summarizes the parameters for this command.
• curveInterpolation–n <name> -d <degree> -p <x y z>: Creates a curve named <name> with degree of the polynomial of <degree> and with points <x y z> used for the interpolation.
• curveInterpolation–n <name> -p <x y z>: Creates a curve named <name> with degree of the polynomial of 3 and with points <x y z> used for the interpolation.

Interactive mode usage:

• Invocation: curveInterpolation
• Parameters:
• Degree of the curve: degree.
• The points used for defining the points of interpolation to form a curve. The number of points specified must minimally be (degree + 1) in order for the interpolation algorithm to work. To finish the insertion of points, press Enter.

Example:

> curveInterpolation

Degree [3]: 3 // (3+1) = 4 points required for interpolation to work.

Select curve points [Press Enter when done]

Point 0 [x y z]: 0 0 0

Point 1 [x y z]: 3 3 0

Point 2 [x y z]: 2 5 1

Point 3 [x y z]: 3 1 3

Point 4 [x y z]:

Result:

Resulting curve
