Methods

Merge

void Merge(const TSphere<T> &rhs)

Merges the two spheres, creating a new sphere that encapsulates them both.

Merge

void Merge(const TVector3<T> &point)

Expands the sphere so it includes the provided point.

Transform

void Transform(const TMatrix4<T> &matrix)

Transforms the sphere by the given matrix.

Contains

bool Contains(const TVector3<T> &v) const

Returns whether or not this sphere contains the provided point.

Intersects

bool Intersects(const TSphere<T> &s) const

Returns whether or not this sphere intersects another sphere.

Intersects

bool Intersects(const TAABox<T> &box) const

Returns whether or not this sphere intersects a box.

Intersects

bool Intersects(const TPlane<T> &plane) const

Returns whether or not this sphere intersects a plane.

Intersects

std::pair<bool, T> Intersects(const TRay<T> &ray, bool discardInside = true) const

Ray/sphere intersection, returns boolean result and distance to nearest intersection.

ray: Ray to intersect with the sphere.
discardInside: (optional) If true the intersection will be discarded if ray origin is located within the sphere.

Merge

void Merge(const TSphere<float> &rhs)

Merges the two spheres, creating a new sphere that encapsulates them both.

Merge

void Merge(const TVector3<float> &point)
