Orient curve

In: Substance Model graph/Modification

Simple

Description

The Orient curve node modifies the orientation of a curve's vertices  – i.e. the arrangement of their normal, tangent and bitangent unit vectors – according to a defined orientation policy. For instance, this node can let you easily invert the direction of a curve.

Parameters

  • Curves to orient Scene
    The input scene holding the curves which orientation should be modified.
  • Basis

    • Basis Scene
      The scene holding the reference Basis to be used.
    • Axis mode Integer
      The arrangement of the axis in the reference Basis.
  • Orientation policy Integer
    The applied rule for orienting the curves. The following options are available:
    • Mostly along: Orient the normal to the interpolated local normal and the tangent in the direction of the curves;
    • Local curve tangent along: Orient the normal to the interpolated local tangent;
    • Local curve normal along: Orient the normal to the interpolated local normal;
    • Local curve bitangent along: Orient the normal to the interpolated local bitangent.
  • Invert Boolean
    Invert the X and Z axes, i.e. the direction of the curves.
