设置曲线法向

设置曲线法向 节点控制每条曲线的法向计算方法。

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 法向节点.

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

最小扭转:

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

Z 向上:

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
