Enum SurfaceKind

#[non_exhaustive]pub enum SurfaceKind {
    Plane,
    Cylinder,
    Cone,
    Sphere,
    Torus,
    Bezier,
    BSpline,
    Revolution,
    Extrusion,
    Trimmed,
    Offset,
}

Expand description

What kind of surface this is, for analytic fast paths.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Plane

A plane.

Cylinder

A circular cylinder.

Cone

A circular cone.

Sphere

A sphere.

Torus

A torus.

Bezier

A polynomial or rational Bézier patch.

BSpline

A polynomial or rational B-spline patch.

Revolution

A surface of revolution.

Extrusion

A surface swept by translating a curve.

Trimmed

A restriction of another surface to a sub-rectangle.

Offset

A surface offset from another.

Implementations§

impl SurfaceKind

pub const fn is_quadric(self) -> bool

Whether this surface is a quadric: a plane, cylinder, cone or sphere.

Quadric pairs have closed-form intersections, which is worth a great deal: it is the difference between an exact conic and a marched approximation of one.

pub const fn is_analytic(self) -> bool

Whether this surface has an exact analytic form, as opposed to being defined by control points.
