pub fn new() -> Self
[src]
pub fn new() -> Self
Create a new clipper object.
pub fn reset(&mut self)
[src]
pub fn reset(&mut self)
Reset the clipper internals, but preserve the allocation.
pub fn add_frustum<V>(
&mut self,
t: &TypedTransform3D<T, U, V>,
bounds: Option<TypedRect<T, V>>
)
[src]
pub fn add_frustum<V>(
&mut self,
t: &TypedTransform3D<T, U, V>,
bounds: Option<TypedRect<T, V>>
)
Add a set of planes that define the frustum for a given transformation.
pub fn add(&mut self, plane: Plane<T, U>)
[src]
pub fn add(&mut self, plane: Plane<T, U>)
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<T, U>) -> &[Polygon<T, U>]
[src]
pub fn clip(&mut self, polygon: Polygon<T, U>) -> &[Polygon<T, U>]
Clip specified polygon by the contained planes, return the fragmented polygons.
pub fn clip_transformed<'a, V>(
&'a mut self,
polygon: Polygon<T, U>,
transform: &'a TypedTransform3D<T, U, V>,
bounds: Option<TypedRect<T, V>>
) -> impl 'a + Iterator<Item = Polygon<T, V>> where
T: Trig,
V: 'a + Debug,
[src]
pub fn clip_transformed<'a, V>(
&'a mut self,
polygon: Polygon<T, U>,
transform: &'a TypedTransform3D<T, U, V>,
bounds: Option<TypedRect<T, V>>
) -> impl 'a + Iterator<Item = Polygon<T, V>> where
T: Trig,
V: 'a + Debug,
Clip the primitive with the frustum of the specified transformation, returning a sequence of polygons in the transformed space.
