Public Member Functions
void	set (vec3 origin, vec3 dir)
	Assign parameters; dir will be normalized.
void	set (vec3 origin, vec3 dir, float maximum)
	Assign parameters; dir will be normalized.
void	setSegment (vec3 a, vec3 b)
	Assign parameters from a line segment.
bit	within (float distance)
	Return whether a distance is within the range.
vec3	strike (box3 box)
	Attempt to strike box with the ray.
vec3	strike (plane3 plane)
	Attempt to strike plane with the ray.
float	strikeDistance (plane3 plane)
	Attempt to strike plane with the ray and return the distance or nan if no strike occurred.
vec3	strike (vec3 a, vec3 b, vec3 c)
	Attempt to strike triangle with the ray.
vec3	strike (vec3[] points)
	Attempt to strike convex polygon with the ray.
Public Attributes
vec3	origin
	Start of the ray.
vec3	dir
	Unit vector pointing in the direction of the ray.
float	maximum
	Maximum distance for valid strikes or nan for none.
float	maximumSquared
	maximum * maximum or nan for none
