metUVWcoördinaten

MetUVWcoördinaten, sometimes referred to as metUVW coordinates, represent a system used in certain computational physics and computer graphics applications to define a coordinate space that is aligned with specific geometric features. The 'met' prefix suggests a context or meta-level, indicating that these coordinates are derived from or related to other, perhaps more fundamental, coordinate systems. The 'UVW' typically stands for the three orthogonal axes within this system, analogous to the more common XYZ.

The primary purpose of metUVWcoördinaten is often to simplify calculations or representations that involve transformations or analyses tied to a particular surface, direction, or orientation. For instance, in the context of discretizing a surface or defining local properties, setting up a UVW coordinate system that intrinsically aligns with the surface's normal and tangent vectors can significantly streamline computations. This is particularly useful in areas like finite element analysis, fluid dynamics simulations on complex geometries, or texture mapping in computer graphics.

The definition of the U, V, and W axes in a metUVW system is context-dependent. The W axis might commonly represent the normal direction to a surface, while U and V span the tangent plane. Alternatively, in other applications, the UVW system might be oriented along specific flow directions or principal stress axes. The key characteristic is that the metUVW system provides a locally adapted and convenient frame of reference for analysis or manipulation.
