AABBTree ​

public void AABBTree<dimension>()

public void AABBTree<dimension>()

brief AABB is a search tree for fast spatial request using the bounding box organisation of elements stored in a single container.

bboxes container containing elements bounding boxes. Each element can then be accessed using the index of its box in the tree which should match the index in its initial container.

nb_bboxes ​

public index_t nb_bboxes()

public index_t nb_bboxes()

brief Gets the number of boxes in the lower level of the aabb tree.

note This value should match the initial size of the container that store all objects to organize the the aabb tree.

bounding_box ​

public const BoundingBox<dimension> & bounding_box()

public const BoundingBox<dimension> & bounding_box()

containing_boxes ​

public vector containing_boxes(const Point<dimension> & query)

public vector containing_boxes(const Point<dimension> & query)

brief Gets all the boxes containing a point

query [in] the point to test

closest_element_box ​

public tuple closest_element_box(const Point<dimension> & query, const EvalDistance & action)

public tuple closest_element_box(const Point<dimension> & query, const EvalDistance & action)

brief Gets the closest element to a point

query [in] the point to test

action [in] the functor to compute the distance between the p and the tree element in boxes

return a tuple containing: - the index of the closest element/box. - the nearest point on the element in box. - the distance between the p and p

EvalDistance this functor should have an operator() defined like this: double operator()( const Point< dimension >& query, index_t curent_element_box ) const ; the output is the distance between the point p and the element stored in thep

note if several elements box match the distance computation, then one of them will be randomly returned.

public void compute_bbox_element_bbox_intersections(const BoundingBox<dimension> & box, EvalIntersection & action)

public void compute_bbox_element_bbox_intersections(const BoundingBox<dimension> & box, EvalIntersection & action)

brief Computes the intersections between a given box and the all element boxes.

box [in] the box to test

action [in] The functor to run when an element box intersectsp

EvalIntersection this functor should have an operator() defined like this: bool operator()( index_t cur_element_box ) ;

note The returned boolean indicates if the search should stop or continue. Return true to stop the search, false to continue.

note the operator define what to do with the box p if it is intersected by the p

public void compute_self_element_bbox_intersections(EvalIntersection & action)

public void compute_self_element_bbox_intersections(EvalIntersection & action)

EvalIntersection this functor should have an operator() defined like this: bool operator()( index_t cur_element_box1, index_t cur_element_box2 );

note cur_element_box1 and cur_element_box2 are the element box indices that intersect.

note the operator defines what to do when two boxes of the tree ( p and p ) intersect each other (for example: test real intersection between each element in boxes and store the result.)

note The returned boolean indicates if the search should stop or continue. Return true to stop the search, false to continue.

EvalIntersection this functor should have an operator() defined like this: bool operator()( index_t cur_element_box1, index_t cur_element_box2 );

note cur_element_box1 and cur_element_box2 are the element box indices that intersect in the current tree and in the other tree.
