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 interfaceRenderObject
- Parameters:
pl
- list of parameters to read fromapi
- reference to the current scene- Returns:
true
if the update is succesfull,false
otherwise
-
inside
protected abstract boolean inside(int x, int y, int z)
-
getBounds
public BoundingBox getBounds()
-
prepareShadingState
public void prepareShadingState(ShadingState state)
Description copied from interface:PrimitiveList
Prepare the specifiedShadingState
by setting all of its internal parameters.- Specified by:
prepareShadingState
in interfacePrimitiveList
- 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 interfacePrimitiveList
- Parameters:
r
- ray in the object's local spaceprimID
- primitive index to intersectstate
- 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 interfacePrimitiveList
- 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 interfacePrimitiveList
- Parameters:
primID
- primitive indexi
- 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 useMatrix4.transform(BoundingBox)
. If the matrix isnull
no transformation is needed, and object space is equivalent to world space.- Specified by:
getWorldBounds
in interfacePrimitiveList
- Parameters:
o2w
- object to world transformation matrix- Returns:
- object bounding box in world space
