Struct FaceDomain

pub struct FaceDomain<'a> { /* private fields */ }

Which parameters of one exact face lie inside it, decided with a certificate or not at all.

The public face of the crate-private Domain: the pcurves of the face’s loops, joined across seams and poles, split into pieces monotone in both parameters so that a ray crossing is decided from the pieces’ ends. contains answers Some(true) or Some(false) only when certain, and None for a point too close to the boundary to say.

Implementations

impl<'a> FaceDomain<'a>

pub fn new( brep: &'a ExactBRep, face: FaceId, tolerance: Tolerance, ) -> Result<Option<FaceDomain<'a>>, ExactMeasureError>

The domain of face, or None when a pcurve family has no monotone split here (a B-spline or intrinsic trim).

Errors

A missing surface, a dangling handle, a boundary that encloses no domain in the surface’s parameters, or an evaluation failure.

pub fn contains(&self, at: DVec2) -> Result<Option<bool>, ExactMeasureError>

Whether the parameters at lie in the face: None when too close to its boundary to decide.

Errors

A pcurve that cannot be evaluated where the decision needs it.

pub fn bounds(&self) -> (DVec2, DVec2)

A box in (u, v) holding the whole domain.
