Trait BuildShell 

pub trait BuildShell {
    // Provided method
    fn tetrahedron(
        points: [impl Into<Point<3>>; 4],
        services: &mut Services,
    ) -> TetrahedronShell { ... }
}

Build a Shell

Provided Methods

fn tetrahedron( points: [impl Into<Point<3>>; 4], services: &mut Services, ) -> TetrahedronShell

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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
