Abstract
Systems, methods, and computer storage mediums are provided for blending custom terrain patches onto a terrain of a virtual three-dimensional environment. A method includes accessing terrain data that describes a mesh representing the surface of the terrain of the three-dimensional environment. The mesh is constructed of primitives that are defined by a terrain altitude at each vertex. A surface grid is determined from the primitives such that each point in the surface grid includes the terrain altitude where the point falls on the mesh. Custom terrain data is also accessed that includes a custom grid of terrain altitudes. A patch grid is determined from the custom grid such that each point in the patch grid includes a terrain altitude derived from the custom grid. The patch and surface grids are blended such that each terrain altitude in the patch grid modifies its corresponding terrain altitude in the surface grid.
