Class FlawedPointHash.FNVHash

java.lang.Object

com.github.yellowstonegames.grid.IPointHash.IntImpl

com.github.yellowstonegames.grid.FlawedPointHash.FNVHash

All Implemented Interfaces:

com.github.yellowstonegames.core.IFlawed, FlawedPointHash, IPointHash

Enclosing interface:

FlawedPointHash

public static class FlawedPointHash.FNVHash
extends IPointHash.IntImpl
implements FlawedPointHash

FNV32a is OK as a hash for bytes when used in some hash tables, but it has major issues on its low-order bits when used as a point hash (the high bits aren't much better). Unfortunately, it is not aesthetically pleasing as a point hash. Some usages might be able to use it to apply a grimy, glitchy effect.
