Struct nannou::geom::tri::Tri [−][src]
A triangle as three vertices.
Implementations
impl<V> Tri<V>
[src]
pub fn from_index_tri(vertices: &[V], indices: &[usize; 3]) -> Self where
V: Clone,
[src]
V: Clone,
Create a Tri by indexing into the given buffer.
Panics if any of the given indices are out of range of the given vertices
slice.
pub fn from_vertices<I>(vertices: I) -> Option<Self> where
I: IntoIterator<Item = V>,
[src]
I: IntoIterator<Item = V>,
Create a Tri from the next three vertices yielded by the given vertices
iterator.
Returns None if there were not at least 3 vertices in the given iterator.
pub fn vertices(self) -> Vertices<V>ⓘ
[src]
Produce an iterator yielding each of the vertices of the triangle.
pub fn centroid(self) -> V where
V: EuclideanSpace,
[src]
V: EuclideanSpace,
Produce the centroid of the triangle aka the “mean”/“average” of all the points.
pub fn map_vertices<F, V2>(self, map: F) -> Tri<V2> where
F: FnMut(V) -> V2,
[src]
F: FnMut(V) -> V2,
Maps the underlying vertices to a new type and returns the resulting Tri
.
pub fn contains(&self, v: &V) -> bool where
V: Vertex2d,
[src]
V: Vertex2d,
Returns true
if the given 2D vertex is contained within the 2D Tri
.
Example
let a = Point2 { x: -0.5, y: 0.0 }; let b = Point2 { x: 0.0, y: 1.0 }; let c = Point2 { x: 0.5, y: -0.75 }; let tri = Tri([a, b, c]); assert!(tri.contains(&Point2 { x: 0.0, y: 0.0 })); assert!(!tri.contains(&Point2 { x: 3.0, y: 3.0 }));
pub fn bounding_rect(self) -> Rect<V::Scalar> where
V: Vertex2d,
[src]
V: Vertex2d,
The bounding Rect
of the triangle.
pub fn bounding_cuboid(self) -> Cuboid<V::Scalar> where
V: Vertex3d,
[src]
V: Vertex3d,
The bounding Rect
of the triangle.
Methods from Deref<Target = [V; 3]>
pub fn as_slice(&self) -> &[T]ⓘ
[src]
array_methods
)Returns a slice containing the entire array. Equivalent to &s[..]
.
pub fn each_ref(&self) -> [&T; N]
[src]
array_methods
)Borrows each element and returns an array of references with the same
size as self
.
Example
#![feature(array_methods)] let floats = [3.1, 2.7, -1.0]; let float_refs: [&f64; 3] = floats.each_ref(); assert_eq!(float_refs, [&3.1, &2.7, &-1.0]);
This method is particularly useful if combined with other methods, like
map
. This way, you can avoid moving the original
array if its elements are not Copy
.
#![feature(array_methods, array_map)] let strings = ["Ferris".to_string(), "♥".to_string(), "Rust".to_string()]; let is_ascii = strings.each_ref().map(|s| s.is_ascii()); assert_eq!(is_ascii, [true, false, true]); // We can still access the original array: it has not been moved. assert_eq!(strings.len(), 3);
