perdirection
Perdirection is a term used in certain fields of vector analysis and data processing to denote the decomposition or evaluation of a quantity with respect to specified directions, rather than in aggregate. The word is formed from the prefix per- meaning through or by, combined with direction, to emphasize a per-directional viewpoint. It is not a widely standardized term across disciplines, but it appears in niche discussions and algorithm descriptions that focus on directional components of a field.
In formal terms, perdirection can be defined for a directional quantity by representing it as a set
Applications of perdirection concepts appear in meteorology, fluid dynamics, robotics, and computer graphics, where understanding how
Computational approaches to perdirection include binning measurements into directional sectors or using continuous angular decompositions, such
