Enum Reach 

pub enum Reach {
    Cone {
        slope: Scalar,
    },
    Tube {
        radius: Scalar,
    },
}

How far from its ray a Pointer reaches: what counts as under it, at any distance along the ray. Everything a viewer draws at a constant size on screen — a handle, a label, a frame datum — is laid out in reaches, so it is hit where it is drawn however far away or zoomed in the view is.

Variants

Cone

Seen in perspective: a cone around the ray, from its origin — the eye — widening by slope per unit of distance.

Fields

slope: Scalar

Tube

Seen orthographically: a tube of radius around the ray.

Fields

radius: Scalar
