Rotasjoner fra gradientretninger

A method can include defining a two dimensional grid of cells for a region associated with a geologic environment, assigning directions to at least some of the cells, tracing a first set of trajectories with respect to the grid based on the directions, determining a first set of scalar field values based on the first set of trajectories, rotating the directions, tracing a second set of trajectories with respect to the grid based on the rotated directions, determining a second set of scalar field values based on the second set of trajectories, outputting a map based on the first set of scalar field values and the second set of scalar field values and applying the map to map a spatially distributed variable in the region associated with the geologic environment. Various other apparatuses, systems, methods, etc., are also disclosed.
