[][src]Struct ncollide2d::shape::Triangle

pub struct Triangle<N: RealField> { /* fields omitted */ }

A triangle shape.


impl<N: RealField> Triangle<N>[src]

pub fn new(a: Point<N>, b: Point<N>, c: Point<N>) -> Triangle<N>[src]

Creates a triangle from three points.

pub fn from_array(arr: &[Point<N>; 3]) -> &Triangle<N>[src]

Creates the reference to a triangle from the reference to an array of three points.

pub fn a(&self) -> &Point<N>[src]

The fist point of this triangle.

pub fn b(&self) -> &Point<N>[src]

The second point of this triangle.

pub fn c(&self) -> &Point<N>[src]

The third point of this triangle.

pub fn vertices(&self) -> &[Point<N>; 3][src]

Reference to an array containing the three vertices of this triangle.

pub fn normal(&self) -> Option<Unit<Vector<N>>>[src]

The normal of this triangle assuming it is oriented ccw.

The normal points such that it is collinear to AB × AC (where × denotes the cross product).

pub fn edges(&self) -> [Segment<N>; 3][src]

The three edges of this triangle: [AB, BC, CA].

pub fn transformed(&self, m: &Isometry<N>) -> Self[src]

Returns a new triangle with vertices transformed by m.

pub fn edges_scaled_directions(&self) -> [Vector<N>; 3][src]

The three edges scaled directions of this triangle: [B - A, C - B, A - C].

pub fn scaled_normal(&self) -> Vector<N>[src]

A vector normal of this triangle.

The vector points such that it is collinear to AB × AC (where × denotes the cross product).

pub fn extents_on_dir(&self, dir: &Unit<Vector<N>>) -> (N, N)[src]

Computes the extents of this triangle on the given direction.

This computes the min and max values of the dot products between each vertex of this triangle and dir.
