摘要: A mechanism for concurrently generating a plurality of meshes is disclosed. A region of a simulated environment for a simulation is determined. An area that bounds the region is determined. The area is decomposed into a plurality of polygons. Data identifying a first elevation layer at locations in the region and a second elevation layer at the locations in the region is accessed. At least some of the polygons are processed based on a first elevation layer metric associated with the first elevation layer and a second elevation layer metric associated with the second elevation layer to concurrently generate a first mesh and a second mesh that include the at least some of the polygons.

摘要: A multi-layer digital elevation model (DEM) structure is disclosed. A device may access a first structure that comprises a plurality of first elevation values and a plurality of location identifiers that may correspond to a geographic region. The first elevation values may be associated with a first layer in the geographic region and correspond to respective location identifiers. The device may access a second structure that identifies a second layer in the geographic region. Second elevation values that may correspond to at least some of the plurality of location identifiers may be determined. A multi-layer DEM structure may be generated that stores the first elevation values and the second elevation values in association with corresponding location identifiers.
