Detailed Description

The basis class for objectset models.

ObjectSet are used to organize object in a faster manner than testing all objects one after an other. Regular grid, n-trees are some examples of such data structures.

Function Documentation

virtual void ObjectSet::add	(	uint32	obj,
		bbox &	bb
	)			[pure virtual, inherited]

Adds a new object ID with its bbox.

Parameters:

	obj	the object ID,
	bb	the bbox.

virtual void ObjectSet::bbox_set

(

bbox &

bb

)

[pure virtual, inherited]

Sets The global bounding box of the ObjectSet.

Parameters:

bb

the global bbox.

virtual void ObjectSet::clear

(

)

[pure virtual, inherited]

Clears the internal datas and is call after each frame computation.

virtual ObjectSet* ObjectSet::duplicate

(

)

[pure virtual, inherited]

Duplicates the object to free parametrized constructor.

virtual uint32 ObjectSet::intersect	(	ray &	r,
		float &	distance,
		packed &	data
	)			[pure virtual, inherited]

Searchs for an intersection with the whole scene but just to have the nearest object, not the full computed intersection.

Parameters:

	r	the ray to test,
	i	the resulting distance (if found),
	data	the private datas to pass to Geometry::compute_intersection.

Returns:

the object ID found (0 if nothing's found).
