Set Curve Normal Node
The Set Curve Normal controls the method used to calculate curve normals for every curve.
The node doesn’t set the normals directly, those are calculated later as necessary. Combined with the tilt attribute value at each control point, this will define the final normals accessible with the Узел Normal (нормаль).
Internally this node adjusts the values of the normal_mode
attribute on each curve.
Входы
- Curve
Standard geometry input, containing curves.
- Selection
Whether or not to change the value on each curve.
Свойства
- Mode
The method for evaluation of the curve’s normals
- Minimum Twist:
The final normals are calculated to have the smallest twist around the curve tangent across the whole curve.
- Z-Up:
The final normals are calculated so that they is perpendicular to the Z axis and the tangent. If a series of points is vertical, the X axis is used
