Method Detail

isFinite

public abstract boolean isFinite()

Overrides:

isFinite in class ASceneObject

getPigment

public void getPigment(mikera.vectorz.Vector3 position,
              mikera.vectorz.Vector3 colourOut)

getProperties

public HashMap<Object,Object> getProperties()

Description copied from interface: ISceneObject

Gets the property map for this scene object

Specified by:

getProperties in interface ISceneObject

Overrides:

getProperties in class ASceneObject

Returns:

getSupport

public abstract double getSupport(mikera.vectorz.Vector3 normal)

Description copied from interface: ISceneObject

Gets the support distance for a given normal direction, i.e. the maximum value of normal.dot(x) for any point x in the scene object

Returns:

getIntersection

public abstract boolean getIntersection(Ray ray,
                      IntersectionInfo result)

Description copied from interface: ISceneObject

Gets the intersection of the scene object with a ray Returns true if an intersection was found, in which case: 1. IntersectionInfo should be populated. 2. The Ray will have its end point reduced to reflect the intersection point

result - Out parameter for populated intersection info if intersection was found, unchanged otherwise
