2Dparametreja
2Dparametreja is a Finnish term used to refer to parameters that depend on two variables, commonly in mathematics and computer graphics. A 2D parameterization is a mapping from a two-dimensional parameter space to a geometric object. The domain is typically a subset of R^2 with coordinates (u, v). The image is a point X(u, v) in the target space, for example in R^2 for curves or in R^3 for surfaces. In 3D modeling, 2D parameterizations are used to describe surfaces by a pair of parameters, often called texture coordinates (u, v) or parameterization coordinates.
Parameterizations can be used to define families of shapes, to describe surfaces, or to map textures. For
