    • 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

    • 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

    • 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

    • 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

    • 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

    • 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
