Constructor and Description 

Ray(float ox,
float oy,
float oz,
float dx,
float dy,
float dz)
Creates a new ray that points from the given origin to the given
direction.

Ray(Point3 a,
Point3 b)
Creates a new ray that points from point a to point b.

Ray(Point3 o,
Vector3 d)
Creates a new ray that points from the given origin to the given
direction.

Modifier and Type  Method and Description 

float 
dot(float vx,
float vy,
float vz)
Computes the dot product of an arbitrary vector with the direction of the
ray.

float 
dot(Vector3 v)
Computes the dot product of an arbitrary vector with the direction of the
ray.

Vector3 
getDirection()
Creates a vector to represent the direction of the ray.

float 
getMax()
Gets the maximum distance along the ray.

float 
getMin()
Gets the minimum distance along the ray  usually 0.

Point3 
getPoint(Point3 dest)
Gets the end point of the ray.

boolean 
isInside(float t)
Checks to see if the specified distance falls within the valid range on
this ray.

void 
normalize()
Normalize the direction component of the ray.

void 
setMax(float t)
Updates the maximum to the specified distance if and only if the new
distance is smaller than the current one.

Ray 
transform(Matrix4 m)
Create a new ray by transforming the supplied one by the given matrix.
