Pituuskenttä

Pituuskenttä, often translated as "length field" or "height field" in English, is a concept used in various fields, particularly in computer graphics and scientific visualization. It is a data structure that represents a two-dimensional surface by storing the height or value at discrete points across a grid. Imagine a landscape where each point on a grid has a corresponding elevation. This is essentially what a pituuskenttä represents.

In practice, a pituuskenttä is typically implemented as a 2D array or a matrix where each element holds a numerical value. This value can represent elevation in terrain modeling, depth in water simulations, temperature in weather forecasting, or any other scalar quantity that varies across a surface. The resolution of the pituuskenttä is determined by the density of the grid points. Higher resolution means more data points and a more detailed representation of the surface.

Rendering a pituuskenttä often involves techniques like triangulation or isosurface extraction to create a smooth, continuous surface from the discrete grid data. These methods allow for the visualization of complex shapes and terrains. The concept is fundamental in generating realistic landscapes for video games, animated films, and scientific simulations, providing a compact and efficient way to store and manipulate surface data.
