Expand description
A tetrahedron with 4 vertices.
Fields
a: OPoint<f32, Const<3_usize>>
The tetrahedron first point.
b: OPoint<f32, Const<3_usize>>
The tetrahedron first point.
c: OPoint<f32, Const<3_usize>>
The tetrahedron first point.

Implementations
Creates a tetrahedron from three points.
Creates the reference to a tetrahedron from the reference to an array of four points.
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.
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.
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.
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.
Computes the barycentric coordinates of the given point in the coordinate system of this tetrahedron.
Returns None
if this tetrahedron is degenerate.
Computes the signed volume of this tetrahedron.
If it is positive, p4
is on the half-space pointed by the normal of the oriented triangle
(p1, p2, p3)
.

Checks if self
is actually part of its subset T
(and can be converted to it).
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.
