Curve Torsion

Functionality

This node calculates the torsion value of a curve at the certain value of curve’s T parameter.

• Number-> A Number

• Curves-> Evaluate Curve

• Viz-> Viewer Draw

• Text-> Stethoscope

• Scene-> Bezier Input

Inputs

This node has the following inputs:

• Curve. The curve to measure torsion for. This input is mandatory.

• T. The value of curve’s T parameter to measure torsion at. The default value is 0.5.

Parameters

This node does not have parameters.

Outputs

This node has the following output:

• Torsion. The torsion value.

Example of usage

Calculate torsion value at several points of some random curve:

• Generator-> Random Vector

• Curves-> Cubic Spline

• Curves-> Curve Domain

• Curves-> Evaluate Curve

• Viz-> Viewer Index+

• Viz-> Viewer Draw

Note that calculating torsion at end points of a curve, or at some other singular points of the curve may give unusable results.
