Description
Sorts a given TPointArray TPA in a spiral pattern, spiraling out from the origin given by Point, using the fast ShellSort algorithm.
Example
var TPA: TPointArray; Pt: TPoint; begin TPA := TPAFromBox(Box(0, 0, 2, 2)); Pt := TPACenter(TPA); SortTPASpiralEx(TPA, Pt); WriteLn(TPAToStr(TPA)); end.
Output:
(1,1);(1,0);(2,0);(2,1);(2,2);(1,2);(0,2);(0,1);(0,0)
