Ray

public Ray()

Ray

public Ray(Ray other)

Ray

public Ray(javax.vecmath.Point3d origin,
 javax.vecmath.Vector3d direction)

Calls Ray(Point3d, Vector3d, double) with the maximum ray distance.

Ray

public Ray(javax.vecmath.Point3d origin,
 javax.vecmath.Vector3d direction,
 double maxDistance)

Parameters:

origin - the camera position.

direction - unit length venctor from camera through viewport and into scene.

maxDistance - the limit to test for ray intersections.

Method Details

getPoint

public javax.vecmath.Vector3d getPoint(double t)

Returns:

start + direction * t

getOrigin
