theory.stanford.edu › ~amitp › GameProgrammingJan 22, 2022 · When D = 1 and D2 = sqrt(2), this is called the octile distance. Another way to write this is D * max(dx, dy) + (D2-D) * min(dx, dy). Patrick Lester writes it yet a different way[6], with if (dx > dy) (D * (dx-dy) + D2 * dy) else (D * (dy-dx) + D2 * dx). These are all equivalent. Euclidean distance#
Octile - definition of Octile by The Free Dictionary
www.thefreedictionary.com › OctileThe initial heuristic used here is the so-called octile distance defined as follows in two-dimensional space: Escaping Depressions in LRTS Based on Incremental Refinement of Encoded Quad-Trees. where h (x) = [absolute value of ( [DELTA]x)] + [absolute value of ( [DELTA]y)] (i.e., Manhattan distance), or h (x) = max ( [absolute value of ( [DELTA]x)], [absolute value of ( [DELTA]y)]) + 0.41 min ( [absolute value of ( [DELTA]x)], [absolute value of ( [DELTA]y)]) (i.e., octile distance), or h {x
