fn tetrahedron( points: [impl Into<Point<3>>; 4], objects: &mut Service<Objects> ) -> Tetrahedron

Build a tetrahedron from the provided points

Accepts 4 points, naturally. For the purposes of the following discussion, let’s call those a, b, c, and d, and assume that the order they are listed in here matches the order they are provided in within the array.

Assumes that a, b, and c form a triangle in counter-clockwise order, when arranging the viewpoint such that it is on the opposite side of the triangle from d. If this assumption is met, the orientation of all faces of the tetrahedron will be valid, meaning their counter-clockwise sides are outside.

Implementation Note

In principle, this method doesn’t need to make assumptions about the order of the points provided. It could, given some extra effort, just build a correct tetrahedron, regardless of that order.
