JuliaFractal
public JuliaFractal()
getBakingPrimitives
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
.
- getBakingPrimitives in interface PrimitiveList
- a list of baking primitives
getNumPrimitives
public int getNumPrimitives()
Returns the number of individual primtives in this aggregate object.
- getNumPrimitives in interface PrimitiveList
getPrimitiveBound
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.
- getPrimitiveBound in interface PrimitiveList
primID
- primitive indexi
- bounding box side index
- value of the request bound
getWorldBounds
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.
- getWorldBounds in interface PrimitiveList
o2w
- object to world transformation matrix
- object bounding box in world space
intersectPrimitive
public void intersectPrimitive(Ray r,
int primID,
IntersectionState state)
Intersect the specified primitive in local space.
- intersectPrimitive in interface PrimitiveList
r
- ray in the object's local spaceprimID
- primitive index to intersectstate
- intersection state
