FE TwistBindOp


Associates points on primitives to driver curves.

The current role of this operator is reattach geometric grass to their derived spines. It may also be useful for similar shapes like scale or feathers.


The Reference Input Surface contains arbitrary geometry, but is presumed to contain on collective piece per primitive, such as a blade of grass.

The Reference Driver Curves should contain the same number of primitives, and it is expected that each curve, in order, loosely follows the shape of the geometric primitive with the same primitive index.


Bindings are stored in the Attach Attribute as a non-normalized one-dimensional CV coordinate along the curve.
