Constructor Details

RayIntersectionImpl

public RayIntersectionImpl(javax.vecmath.Point3d position,
 javax.vecmath.Vector3d normal,
 MeshTriangleImpl tri,
 boolean directHit)

Constructor.

Parameters:

position - Intersection position, must not be null

normal - normal of MeshPoint

tri - triangle with which the ray intersects. Must not be null

directHit - determines whether the position is in the ray's direction

Throws:

IllegalArgumentException - if some parameter is null

Method Details

getDistance

public double getDistance()

Description copied from interface: RayIntersection

Returns distance from the ray's origin to this ray intersection.

Specified by:

getDistance in interface RayIntersection

Returns:

distance from the ray's origin to this ray intersection

getHitTriangle

public MeshTriangle getHitTriangle()

Description copied from interface: RayIntersection

Returns hit triangle

Specified by:

getHitTriangle in interface RayIntersection

Returns:

hit triangle

isDirectHit

public boolean isDirectHit()

Description copied from interface: RayIntersection

Determines if the ray intersection is in the direction of the ray (direct hit) or i opposite direction (indirect hit)

Specified by:

isDirectHit in interface RayIntersection

Returns:

true if the hit is in the ray's direction

setDistance

public void setDistance(javax.vecmath.Point3d rayOrigin)

Description copied from interface: RayIntersection

Set the distance of the intersection point from the ray's origin. If the intersection point lies in the opposite direction than ray's normal, then a negative distance is set.

Specified by:

setDistance in interface RayIntersection

Parameters:

rayOrigin - The origin of the ray that has been used to compute this intersection

hashCode

public int hashCode()

Overrides:

hashCode in class MeshPointImpl

equals

public boolean equals(Object obj)

Overrides:

equals in class MeshPointImpl

compareTo

public int compareTo(RayIntersection o)

Specified by:

compareTo in interface Comparable<RayIntersection>

Specified by:

compareTo in interface RayIntersection
