[][src]Struct nannou::geom::tri::Tri

pub struct Tri<V = Default>(pub [V; 3]);

A triangle as three vertices.

Methods

impl<V> Tri<V> where
    V: Vertex
[src]

pub fn from_index_tri(vertices: &[V], indices: &[usize; 3]) -> Self where
    V: Vertex
[src]

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]

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.

Important traits for Vertices<V>
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]

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]

Maps the underlying vertices to a new type and returns the resulting Tri.

impl<V> Tri<V> where
    V: Vertex2d
[src]

pub fn contains(&self, v: &V) -> bool where
    V: Vertex2d
[src]

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]

The bounding Rect of the triangle.

pub fn bounding_cuboid(self) -> Cuboid<V::Scalar> where
    V: Vertex3d
[src]

The bounding Rect of the triangle.
