The *Curve Tangent* node outputs the direction that a curve points in at each control point,
|
|
depending on the direction of the curve (which can be controlled with
|
|
the :doc:`/modeling/geometry_nodes/curve/operations/reverse_curve`). The output values are normalized vectors.
|
|
|
|
.. warning::
|
|
|
|
For NURBS and Bézier spline curves, keep in mind that the value retrieved from this node is
|
|
the value at every control point, which may not correspond to the visible *evaluated* points.
|
|
For example, a Bézier spline might have 48 evaluated points, but only four control points,
|
|
if its resolution is 12. For NURBS splines the difference may be even more pronounced and the result
|
|
may not be as expected. A :doc:`/modeling/geometry_nodes/curve/operations/resample_curve` can be used to
|
|
create a poly spline, where there is a control point for every evaluated point.
