Module bounding

This module contains traits and implements for working with bounding shapes

There are four traits used:

• BoundingVolume is a generic abstraction for any bounding volume
• IntersectsVolume abstracts intersection tests against a BoundingVolume
• Bounded2d/Bounded3d are abstractions for shapes to generate BoundingVolumes

Structs

Aabb2d

A 2D axis-aligned bounding box, or bounding rectangle

Aabb3d

A 3D axis-aligned bounding box

AabbCast2d

An intersection test that casts an Aabb2d along a ray.

AabbCast3d

An intersection test that casts an Aabb3d along a ray.

BoundingCircle

A bounding circle

BoundingCircleCast

An intersection test that casts a BoundingCircle along a ray.

BoundingSphere

A bounding sphere

BoundingSphereCast

An intersection test that casts a BoundingSphere along a ray.

RayCast2d

A raycast intersection test for 2D bounding volumes

RayCast3d

A raycast intersection test for 3D bounding volumes

Traits

Bounded2d

A trait with methods that return 2D bounding volumes for a shape.

Bounded3d

A trait with methods that return 3D bounding volumes for a shape.

BoundedExtrusion

A trait implemented on 2D shapes which determines the 3D bounding volumes of their extrusions.

BoundingVolume

A trait that generalizes different bounding volumes. Bounding volumes are simplified shapes that are used to get simpler ways to check for overlapping elements or finding intersections.

IntersectsVolume

A trait that generalizes intersection tests against a volume. Intersection tests can be used for a variety of tasks, for example:
