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 Normal(ノーマル)ノード.

Internally this node adjusts the values of the normal_mode attribute on each curve.

入力

Curve(カーブ)

Standard geometry input, containing curves.

Selection(選択)

Whether or not to change the value on each curve.

Properties(プロパティ)

Mode(モード)

The method for evaluation of the curve's normals

Minumum 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
