Abstract
Methods and apparatus are provided for processing data representing three-dimensional points organized in a data structure wherein each point has multiple components, the data is organized in a respective layer per component, each layer is segmented in cells of a two-dimensional grid, the cells are arranged such that the components of a given point are contained in corresponding cells of multiple layers, the cells are grouped in patches by layer, and the patches are arranged such that the components of an array of points is represented by corresponding patches of multiple layers. At least one first criterion and at least one second criterion are obtained. Data are retrieved from cells of patches meeting the at least one first criterion and from layers meeting the at least one second criterion. The retrieved data are processed to obtain a derivative data set.
