Curve Root¶
The Curve Root node outputs information related to the root point of each curve. It is commonly used in hair grooming and procedural setups to anchor deformations, apply transformations relative to the curve base, or isolate operations affecting only the roots.
Inputs¶
This node has no inputs.
Outputs¶
- Root Selection
A boolean selection that is
trueonly for the root points of curves. This is useful for applying operations exclusively at the curve base.- Root Position
The position of each curve’s root point in 3D space. This can be used for aligning objects, sampling data from a surface, or generating root-based effects.
- Root Direction
A normalized vector representing the direction of the first segment of the curve, pointing away from the root toward the next control point. This is useful for orienting instances or determining the initial growth direction of the curve.
- Root Index
The index of the root point for each curve. This is typically 0 for every curve, but it can be used to identify root points when processing multiple curves together.
