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