Detailed Description

Bounding sphere defined by a center point and radius.

Member Function Documentation

Contains()

bool Crux::BoundingSphere::Contains ( const vec3 & point ) const

inlineconstexpr

Tests whether a point lies inside or on the surface of this sphere.

Parameters

point

The point to test.

Returns

True if the squared distance from the center to point is within the squared radius.

FromAABB()

BoundingSphere Crux::BoundingSphere::FromAABB ( const AABB & aabb )

inlinestatic

Constructs the smallest bounding sphere enclosing the given AABB.

Parameters

aabb	The AABB to enclose.

Returns

A sphere centered at the AABB center with radius equal to the half-diagonal.

FromCenterRadius()

constexpr BoundingSphere Crux::BoundingSphere::FromCenterRadius ( const vec3 & center, f32 radius )

inlinestaticconstexpr

Constructs a bounding sphere from an explicit center and radius.

Parameters

center	The center of the sphere.
radius	The radius of the sphere.

Returns

A BoundingSphere with the given center and radius.

Intersects() [1/2]

bool Crux::BoundingSphere::Intersects ( const AABB & aabb ) const

inlineconstexpr

Tests whether this sphere overlaps an AABB.

Parameters

aabb	The AABB to test against.

Returns

True if the closest point on the AABB to the sphere center is within the radius.

Intersects() [2/2]

bool Crux::BoundingSphere::Intersects ( const BoundingSphere & other ) const

inlineconstexpr

Tests whether this sphere overlaps another sphere.

Uses squared distance to avoid a sqrt.

Parameters

other

The sphere to test against.

Returns

True if the distance between centers is less than or equal to the sum of radii.
