[−][src]Struct nannou::geom::quad::Quad
A quad represented by its four vertices.
Implementations
impl<V> Quad<V> where
V: Vertex,
[src]
V: Vertex,
pub fn vertices(self) -> Vertices<V>ⓘ
[src]
Produce an iterator yielding each vertex in the Quad
.
pub fn centroid(&self) -> V where
V: EuclideanSpace,
[src]
V: EuclideanSpace,
Produce the centroid of the quad, aka the "mean"/"average" vertex.
pub fn triangles(&self) -> (Tri<V>, Tri<V>)
[src]
Triangulates the given quad, represented by four points that describe its edges in either clockwise or anti-clockwise order.
Example
The following rectangle
a b -------- | | | | | | -------- d c
given as
triangles([a, b, c, d])
returns
(Tri([a, b, c]), Tri([a, c, d]))
Here's a basic code example:
use nannou::geom::{self, pt2, Quad, Tri}; fn main() { let a = pt2(0.0, 1.0); let b = pt2(1.0, 1.0); let c = pt2(1.0, 0.0); let d = pt2(0.0, 0.0); let quad = Quad([a, b, c, d]); let triangles = geom::quad::triangles(&quad); assert_eq!(triangles, (Tri([a, b, c]), Tri([a, c, d]))); }
pub fn triangles_iter(&self) -> Triangles<V>ⓘ
[src]
The same as triangles
but provided as an Iterator.
pub fn bounding_rect(self) -> Rect<V::Scalar> where
V: Vertex2d,
[src]
V: Vertex2d,
The bounding Rect
of the quad.
pub fn bounding_cuboid(self) -> Cuboid<V::Scalar> where
V: Vertex3d,
[src]
V: Vertex3d,
The bounding Rect
of the triangle.
pub fn map_vertices<F, V2>(self, map: F) -> Quad<V2> where
F: FnMut(V) -> V2,
[src]
F: FnMut(V) -> V2,
Map the Quad's vertices to a new type.
Methods from Deref<Target = [V; 4]>
pub fn as_slice(&self) -> &[T]ⓘ
[src]
array_methods
)Returns a slice containing the entire array. Equivalent to &s[..]
.
