Struct SurfaceSeeds 

pub struct SurfaceSeeds { /* private fields */ }

A surface’s seeding structure, built once and asked many times.

project_on_surface builds the same seeding structure for every call: a B-spline patch’s span boxes, or a grid of surface points for a surface with no closed form. A caller projecting many targets onto one surface builds it once, and each projection reduces to the search plus the Newton polish: the same seeds, the same refinement, the same answer to the bit.

Implementations

impl SurfaceSeeds

pub fn over( surface: &SurfaceGeometry, samples: usize, tol: Tolerances, ) -> OgeomResult<Self>

Build the seeding structure project_on_surface would use, once.

Errors

Never for a well-formed surface; evaluation failures leave gaps in the grid exactly as the per-call version tolerates them.

pub fn project( &self, surface: &SurfaceGeometry, target: Point, tol: Tolerances, ) -> OgeomResult<SurfaceProjection>

Project target, seeded from the stored structure, bit-identical to project_on_surface at the same sample count.

Errors

As project_on_surface.
