    sheet: &NurbsSurface,
    pcurve: &NurbsCurve,
) -> Result<NurbsCurve, String>
Expand description

Exact 3D image of a pcurve on an AFFINE sheet: an affine map applied to the homogeneous control points commutes with the rational evaluation, so the image shares the pcurve’s degree / knots / weights and is parametrized identically — a rational circle pcurve maps to the exact 3D circle.
