Struct Face 

pub struct Face<'m> { /* private fields */ }

A bounded face of a solid (ADVANCED_FACE / FACE_SURFACE) — a surface trimmed by boundary loops, with an orientation.

Implementations

impl<'m> Face<'m>

pub fn name(&self) -> &'m str

pub fn same_sense(&self) -> bool

pub fn surface(&self) -> Surface<'m>

The underlying (unbounded) surface this face sits on.

pub fn bounds(&self) -> impl Iterator<Item = Bound<'m>> + 'm

The boundary loops trimming this face.

pub fn to_nurbs(&self) -> Option<NurbsSurface>

The NURBS (NurbsSurface) form of this face’s geometry. A closed analytic surface (sphere, torus, B-spline) is returned whole via Surface::to_nurbs. An unbounded surface (plane, cylinder, cone, linear extrusion) is sized to the control points of its boundary edges’ NURBS forms — a guaranteed cover of the boundary — and is the untrimmed base patch (the edge loops trim it separately). None if the kind is unsupported or the bounds are degenerate.

pub fn key(&self) -> EntityKey

This face’s global identity (a Copy key for maps / deduplication; two handles to the same entity share one key()).

pub fn color(&self) -> Option<Rgb>

The colour styled onto this face, if any.

pub fn transparency(&self) -> Option<f64>

The transparency styled onto this face (0.0 opaque … 1.0 fully transparent), if any.

pub fn layer(&self) -> Option<&'m str>

The name of the presentation layer this face belongs to, if any.

pub fn is_visible(&self) -> bool

Whether this face is visible — false if an INVISIBILITY hides it (via its styled item or its layer). Defaults to visible.

pub fn solid(&self) -> Option<Solid<'m>>

The b-rep solid this face belongs to, if any (reverse: a CLOSED_SHELL listing this face → a MANIFOLD_SOLID_BREP or BREP_WITH_VOIDS whose shell is that shell, directly or through an ORIENTED_CLOSED_SHELL).

Trait Implementations

impl<'m> Clone for Face<'m>

fn clone(&self) -> Face<'m>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
