Method Detail

getIntersectionData

public IsectData3D getIntersectionData()

Specified by:

getIntersectionData in interface Intersector3D

Returns:

intersection data parcel

getReflectedRayPointAtDistance

public ReadonlyVec3D getReflectedRayPointAtDistance(float dist)

Description copied from interface: Reflector3D

Returns the point on the reflected ray at given distance from the intersection point

Specified by:

getReflectedRayPointAtDistance in interface Reflector3D

Parameters:

dist - distance from isect position

Returns:

point on reflected ray

getReflectionAngle

public float getReflectionAngle()

Specified by:

getReflectionAngle in interface Reflector3D

Returns:

angle between incident ray and surface normal

getSphere

public Sphere getSphere()

Returns:

the sphere

intersectRayDistance

public float intersectRayDistance(Ray3D ray)

Calculates the distance of the vector to the given sphere in the specified direction. A sphere is defined by a 3D point and a radius. Normalized directional vectors expected.

Parameters:

ray - intersection ray

Returns:

distance to sphere in world units, -1 if no intersection.

intersectsRay

public boolean intersectsRay(Ray3D ray)

Description copied from interface: Intersector3D

Checks if entity intersects with the given ray. Further intersection details can then be queried via the IsectData3D instance returned by Intersector3D.getIntersectionData().

Specified by:

intersectsRay in interface Intersector3D

Parameters:

ray - ray to check

Returns:

true, if ray hits the entity

reflectRay

public Ray3D reflectRay(Ray3D ray)

Description copied from interface: Reflector3D

Reflects given ray on the entity's surface

Specified by:

reflectRay in interface Reflector3D

Parameters:

ray - incident ray

Returns:

reflected ray starting from intersection point

setSphere

public void setSphere(Sphere sphere)

Parameters:

sphere - the sphere to set
