Wrangle Node
Example - Calculate Vectors for Normal on Curve
Posted on Mar 11 2018
Suppose you have a curve and you need to calculate the direction to copy geometry onto this. Polyframe works in some cases, but here is a robust version using point wrangle nodes. The hipnc is provided as well (created in 16.5.268).
Take the point and the next point and subtract to get the tangent vector. Note at the end, there is no next point so you have to deal with this by taking the previous point and reversing the vector. Code below.
