A smooth B-spline curve shaped by a list of control points. It starts at the first point and ends at the last, and is pulled toward, not through, the points between.
The points that shape the curve, in order (at least two).
Degree, from a wire; replaces the typed value.
Values the block gives besides its output. The editor lists them under Properties, and an input can read one by reference.
Where the curve begins.
Where the curve ends.
The curve's unit direction at its start.
The curve's unit direction at its end.
Unit vector along the straight chord from start to end.
Length measured along the curve.
The center of the curve's bounding box.
The axis-aligned extent of the curve.
Distance to the curve as a field, zero on the curve.
At each point, how far along the curve its nearest curve point lies (computed on the CPU only).
The display name of the node that made the curve.
The same curve, running from end to start.
The points that shape the spline.
Polynomial degree of the spline (3 for Catmull-Rom).
True when the spline loops back to its start.
