pub fn face(&self, i: usize) -> Triangle<N>

Returns the i-th face of this tetrahedron.

The 0-th face is the triangle ABC. The 1-st face is the triangle ABD. The 2-nd face is the triangle ACD. The 3-rd face is the triangle BCD.

pub fn face_ids(i: usize) -> (usize, usize, usize)

Returns the i-th face of this tetrahedron.

The 0-th face is the triangle ABC. The 1-st face is the triangle ABD. The 2-nd face is the triangle ACD. The 3-rd face is the triangle BCD.

pub fn edge(&self, i: usize) -> Segment<N>

Returns the i-th edge of this tetrahedron.

The 0-st edge is the segment AB. The 1-st edge is the segment AC. The 2-nd edge is the segment AD. The 3-rd edge is the segment BC. The 4-th edge is the segment BD. The 5-th edge is the segment CD.

pub fn edge_ids(i: usize) -> (usize, usize)

Returns the indices of the vertices of the i-th edge of this tetrahedron.

The 0-st edge is the segment AB. The 1-st edge is the segment AC. The 2-nd edge is the segment AD. The 3-rd edge is the segment BC. The 4-th edge is the segment BD. The 5-th edge is the segment CD.

pub fn barycentric_coordinates(&self, p: &Point<N>) -> Option<[N; 4]>

Computes the barycentric coordinates of the given point in the coordinate system of this tetrahedron.

Returns None if this tetrahedron is degenerate.
