Interpolate Curves Node
Generate new curves on points by interpolating between existing curves. This is useful to have a smaller set of original curves to make editing easier and faster while still generating high-density curves for the viewport or a final render.
- Guide Curves
Base curves that new curves are interpolated between.
- Guide Up
Optional up vector that is typically a surface normal. Supplying an up vector will improve the quality of the interpolation, making it aware of the surface shape which it otherwise wouldn't have a way to know about.
- Guide Group ID
Splits guides into separate groups. New curves interpolate existing curves from a single group. This input can be useful for generating hair parts by stopping curves in different sections (with different group IDs) from affecting each other.
The positions of the first root control points of the newly generated interpolated curves.
- Points Up
Optional up vector that is typically a surface normal.
- Point Group ID
The curve group to interpolate in.
- Max Neighbor
Maximum amount of close guide curves that are taken into account for interpolation.
The guide curves with interpolated curves.
- Closest Index
Index of the closest guide curve for each generated curve.
Internally this node mixes the data from multiple guide curves, with the maximum number of sources depending on the Max Neighbor input. This output is only the index of the curve with the largest weight.
- Closest Weight
Weight of the closest guide curve for each generated curve.
