Data Structures
struct	PTK_GridCircleIter
	Grid circle iterators are intended to be mostly opaque structures which can produce a sequence of (x,y) pairs covering the interior of a circle using a minimal number of operations aggregated across the entire iteration. It does not produce any points outside the circle. Grid circle iterators operates on cell coordinates. More...
struct	PTK_GridIter_PhysBox
	Grid box (rectangle) iterators produce a sequence of the cell coordinates which lie inside a rectangle defined in physical grid coordinates. More...

Functions
void	PTK_GridCircleIterInit (PTK_GridCircleIter *iter, const PTK_Grid *grid, const PTK_GridRoi *roi, int32_t cx, int32_t cy, uint32_t r)
	Initializes the grid iterator. More...
uint32_t	PTK_GridCircleIterNext (PTK_GridCircleIter *iter, uint32_t *cellX, uint32_t *cellY)
	Returns the next cell inside the region of interest. More...
void	PTK_GridIter_PhysBoxInit (PTK_GridIter_PhysBox *iter, const PTK_Grid *grid, const PTK_GridRoi *roi)
	Initialize the iterator. More...
uint32_t	PTK_GridIter_PhysBoxGetNext (PTK_GridIter_PhysBox *iter, uint32_t *cellX, uint32_t *cellY)
	Get next cell from iterator. When no more cells are available, return 0. More...
