Enum PipeLaw 

pub enum PipeLaw<'a> {
    RotationMinimizing,
    Frenet,
    Auxiliary {
        guide: &'a Shape,
    },
    Binormal(Direction),
    Fixed,
}

How a pipe’s section turns about its spine.

Variants

RotationMinimizing

Double-reflection rotation-minimizing frames: the section neither twists nor kinks where the spine bends.

Frenet

The Frenet frame, turning with the spine’s own curvature.

Auxiliary

The section’s normal axis points at guide, a curve running beside the spine: at each station, where the guide crosses the plane square to the spine there.

Fields

guide: &'a Shape

An edge or wire beside the spine.

Binormal(Direction)

The section keeps this direction as its binormal, square to the spine’s tangent.

Fixed

The section keeps the frame it has at the spine’s start all the way: carried by translation along the spine, never turned.
