Nodo Definir normal de curva

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 Nodo Normal.

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

Entradas

Curva

Entrada estándar de geometría, conteniendo curvas.

Selección

Whether or not to change the value on each curve.

Propiedades

Modo

The method for evaluation of the curve’s normals

Torsión mínima:

The final normals are calculated to have the smallest twist around the curve tangent across the whole curve.

+Z hacia arriba:

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
