Method Detail

• update

  public boolean update(ParameterList pl,
                        SunflowAPI api)

  Description copied from interface: RenderObject
  Update this object given a list of parameters. This method is guarenteed to be called at least once on every object, but it should correctly handle empty parameter lists. This means that the object should be in a valid state from the time it is constructed. This method should also return true or false depending on whether the update was succesfull or not.

  Specified by:

  update in interface RenderObject

  Parameters:

  pl - list of parameters to read from

  api - reference to the current scene

  Returns:

  true if the update is succesfull, false otherwise

• prepareShadingState

  public void prepareShadingState(ShadingState state)

  Description copied from interface: PrimitiveList
  Prepare the specified ShadingState by setting all of its internal parameters.

  Specified by:

  prepareShadingState in interface PrimitiveList

  Parameters:

  state - shading state to fill in

• intersectPrimitive

  public void intersectPrimitive(Ray r,
                                 int primID,
                                 IntersectionState state)

  Description copied from interface: PrimitiveList
  Intersect the specified primitive in local space.

  Specified by:

  intersectPrimitive in interface PrimitiveList

  Parameters:

  r - ray in the object's local space

  primID - primitive index to intersect

  state - intersection state

  See Also:

  Ray.setMax(float), IntersectionState.setIntersection(int, float, float)

• getNumPrimitives

  public int getNumPrimitives()

  Description copied from interface: PrimitiveList
  Returns the number of individual primtives in this aggregate object.

  Specified by:

  getNumPrimitives in interface PrimitiveList

  Returns:

  number of primitives

• getPrimitiveBound

  public float getPrimitiveBound(int primID,
                                 int i)

  Description copied from interface: PrimitiveList
  Retrieve the bounding box component of a particular primitive in object space. Even indexes get minimum values, while odd indexes get the maximum values for each axis.

  Specified by:

  getPrimitiveBound in interface PrimitiveList

  Parameters:

  primID - primitive index

  i - bounding box side index

  Returns:

  value of the request bound

• getWorldBounds

  public BoundingBox getWorldBounds(Matrix4 o2w)

  Description copied from interface: PrimitiveList
  Compute a bounding box of this object in world space, using the specified object-to-world transformation matrix. The bounds should be as exact as possible, if they are difficult or expensive to compute exactly, you may use Matrix4.transform(BoundingBox). If the matrix is null no transformation is needed, and object space is equivalent to world space.

  Specified by:

  getWorldBounds in interface PrimitiveList

  Parameters:

  o2w - object to world transformation matrix

  Returns:

  object bounding box in world space

• getBakingPrimitives

  public PrimitiveList getBakingPrimitives()

  Description copied from interface: PrimitiveList
  Create a new PrimitiveList object suitable for baking lightmaps. This means a set of primitives laid out in the unit square UV space. This method is optional, objects which do not support it should simply return null.

  Specified by:

  getBakingPrimitives in interface PrimitiveList

  Returns:

  a list of baking primitives
