#include <PointsGrid.h>

Classes
struct	GridElement
	Checks if a grid position is already visited by NextOnRay(). More...
Public Member Functions
Base::BoundBox3d	GetBoundBox (void) const
	Returns the bounding box of the current grid element.
void	GetElements (std::vector< unsigned long > &raulElements) const
	Returns indices of the elements in the current grid.
void	GetGridPos (unsigned long &rulX, unsigned long &rulY, unsigned long &rulZ) const
	Returns the grid number of the current position.
	PointsGridIterator (const PointsGrid &rclG)
	Construction.
Iteration

void	Init (void)
	Sets the iterator to the first element.
bool	More (void) const
	Checks if the iterator has not yet reached the end position.
void	Next (void)
	Go to the next grid.
Tests with rays

bool	InitOnRay (const Base::Vector3d &rclPt, const Base::Vector3d &rclDir, float fMaxSearchArea, std::vector< unsigned long > &raulElements)
	Searches for facets around the ray.
bool	InitOnRay (const Base::Vector3d &rclPt, const Base::Vector3d &rclDir, std::vector< unsigned long > &raulElements)
	Searches for facets around the ray.
bool	NextOnRay (std::vector< unsigned long > &raulElements)
	Searches for facets around the ray.
