Expand description

A convex polygon in 3D.

Vertices are assumed to be ordered counter-clockwise.

Required Methods§

source

fn num_vertices(&self) -> usize

source

fn get_vertex(&self, index: usize) -> Option<Point3<T>>

Provided Methods§

source

fn compute_plane(&self) -> Option<Plane<T>>where
T: Real,

source

fn compute_half_space(&self) -> Option<HalfSpace<T>>where
T: Real,

source

fn compute_area_vector(&self) -> Vector3<T>where
T: Real,

Computes a vector normal to the polygon (oriented outwards w.r.t. a counter-clockwise orientation), whose absolute magnitude is the area of the polygon.

Note that if the polygon is non-planar or not properly oriented, there are no guarantees on the quality of the result.
