Struct plane_split::Clipper

pub struct Clipper<A> { /* private fields */ }

A helper object to clip polygons by a number of planes.

Implementations

impl<A: Copy + Debug> Clipper<A>

pub fn new() -> Self

Create a new clipper object.

pub fn reset(&mut self)

Reset the clipper internals, but preserve the allocation.

pub fn frustum_planes(
    t: &Transform3D<f64>,
    bounds: Option<Rect<f64>>
) -> Result<impl Iterator<Item = Plane>, NegativeHemisphereError>

Extract the clipping planes that define the frustum for a given transformation.

pub fn add(&mut self, plane: Plane)

Add a clipping plane to the list. The plane will clip everything behind it, where the direction is set by the plane normal.

pub fn clip(&mut self, polygon: Polygon<A>) -> &[Polygon<A>]

Clip specified polygon by the contained planes, return the fragmented polygons.

pub fn clip_transformed<'a>(
    &'a mut self,
    polygon: Polygon<A>,
    transform: &'a Transform3D<f64>,
    bounds: Option<Rect<f64>>
) -> Result<impl 'a + Iterator<Item = Polygon<A>>, NegativeHemisphereError>

Clip the primitive with the frustum of the specified transformation, returning a sequence of polygons in the transformed space. Returns None if the transformation can’t be frustum clipped.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
