public PrimitiveList getBakingPrimitives()

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

public int getNumPrimitives()

Returns the number of individual primtives in this aggregate object.

Specified by:

getNumPrimitives in interface PrimitiveList

Returns:

number of primitives

public float getPrimitiveBound(int primID,
                               int i)

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

public BoundingBox getWorldBounds(Matrix4 o2w)

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

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

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

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

public void prepareShadingState(ShadingState state)

Prepare the specified ShadingState by setting all of its internal parameters.

Specified by:

prepareShadingState in interface PrimitiveList

Parameters:

state - shading state to fill in

public boolean update(ParameterList pl,
                      SunflowAPI api)

Specified by:

update in interface RenderObject
