Method Details

intersects

public boolean intersects(javax.vecmath.Point3d point,
 double epsilon)

Parameters:

point - the point to test

epsilon - how close to the plane is close enough

Returns:

true if the point is on the plane

intersects

public boolean intersects(javax.vecmath.Point3d point)

Parameters:

point - the point to test

Returns:

true if the point is within 0.0001 of the plane.

intersectDistance

public double intersectDistance(Ray ray)

finds the intersection of a ray and this plane.

Parameters:

ray - the ray to intersect.

Returns:

the distance along the ray to the intersection point. NaN if no intersection.

intersect

public boolean intersect(Ray r,
 javax.vecmath.Point3d intersection)

set

public void set(Plane arg0)

set this plane to the same values as arg0

Parameters:

arg0 -

getNormal
