Struct fj_kernel::objects::FaceBRep

pub struct FaceBRep {
    pub surface: Surface,
    pub exteriors: CyclesInFace,
    pub interiors: CyclesInFace,
    pub color: [u8; 4],
}

The boundary representation of a face

This type exists to ease the handling of faces that use boundary representation. It will eventually be merged into Face, once Face::Triangles can finally be removed.

Fields

surface: Surface

The surface that defines this face

exteriors: CyclesInFace

The cycles that bound the face on the outside

Implementation Note

Since these cycles bound the face, the edges they consist of must lie in the surface. The data we’re using here is 3-dimensional though, so no such limitation is enforced.

It might be less error-prone to specify the cycles in surface coordinates.

interiors: CyclesInFace

The cycles that bound the face on the inside

Each of these cycles defines a hole in the face.

Implementation note

See note on exterior field.

color: [u8; 4]

The color of the face

Implementations

impl FaceBRep

pub fn surface(&self) -> Surface

Access this face’s surface

pub fn exteriors(&self) -> impl Iterator<Item = Cycle> + '_

Access this face’s exterior cycles

pub fn interiors(&self) -> impl Iterator<Item = Cycle> + '_

Access this face’s interior cycles

pub fn all_cycles(&self) -> impl Iterator<Item = Cycle> + '_

Access all cycles of this face

This is equivalent to chaining the iterators returned by Face::exteriors and Face::interiors.

Trait Implementations
