Public Member Functions
	Ray () noexcept=default
	Construct a degenerate ray with zero origin and direction.
	Ray (const Vector3 &origin, const Vector3 &direction) noexcept
	Construct from origin and direction. The direction will be normalized.
	Ray (const Ray &ray) noexcept=default
	Copy-construct from another ray.
Ray &	operator= (const Ray &rhs) noexcept=default
	Assign from another ray.
bool	operator== (const Ray &rhs) const
	Check for equality with another ray.
bool	operator!= (const Ray &rhs) const
	Check for inequality with another ray.
void	Define (const Vector3 &origin, const Vector3 &direction)
	Define from origin and direction. The direction will be normalized.
Vector3	Project (const Vector3 &point) const
	Project a point on the ray.
float	Distance (const Vector3 &point) const
	Return distance of a point from the ray.
Vector3	ClosestPoint (const Ray &ray) const
	Return closest point to another ray.
float	HitDistance (const Plane &plane) const
	Return hit distance to a plane, or infinity if no hit.
float	HitDistance (const BoundingBox &box) const
	Return hit distance to a bounding box, or infinity if no hit.
float	HitDistance (const Frustum &frustum, bool solidInside=true) const
	Return hit distance to a frustum, or infinity if no hit. If solidInside parameter is true (default) rays originating from inside return zero distance, otherwise the distance to the closest plane.
float	HitDistance (const Sphere &sphere) const
	Return hit distance to a sphere, or infinity if no hit.
float	HitDistance (const Vector3 &v0, const Vector3 &v1, const Vector3 &v2, Vector3 *outNormal=nullptr, Vector3 *outBary=nullptr) const
	Return hit distance to a triangle, or infinity if no hit. Optionally return hit normal and hit barycentric coordinate at intersect point.
float	HitDistance (const void *vertexData, unsigned vertexStride, unsigned vertexStart, unsigned vertexCount, Vector3 *outNormal=nullptr, Vector2 *outUV=nullptr, unsigned uvOffset=0) const
	Return hit distance to non-indexed geometry data, or infinity if no hit. Optionally return hit normal and hit uv coordinates at intersect point.
float	HitDistance (const void *vertexData, unsigned vertexStride, const void *indexData, unsigned indexSize, unsigned indexStart, unsigned indexCount, Vector3 *outNormal=nullptr, Vector2 *outUV=nullptr, unsigned uvOffset=0) const
	Return hit distance to indexed geometry data, or infinity if no hit. Optionally return hit normal and hit uv coordinates at intersect point.
bool	InsideGeometry (const void *vertexData, unsigned vertexSize, unsigned vertexStart, unsigned vertexCount) const
	Return whether ray is inside non-indexed geometry.
bool	InsideGeometry (const void *vertexData, unsigned vertexSize, const void *indexData, unsigned indexSize, unsigned indexStart, unsigned indexCount) const
	Return whether ray is inside indexed geometry.
Ray	Transformed (const Matrix3x4 &transform) const
	Return transformed by a 3x4 matrix. This may result in a non-normalized direction.

Public Attributes
Vector3	origin_
	Ray origin.
Vector3	direction_
	Ray direction.
