Abstract: In a power line communication (PLC) method, a primary routing device may obtain a device access status of a first secondary routing device. When a device access status of a first secondary routing device is a first state, it indicates that no user equipment accesses a first secondary routing device. In this case, a primary routing device may allocate a transmission opportunity in a second time segment subsequent to a first time segment of a transmission management cycle to the first secondary routing device.

Abstract: A method and system provide the ability to design a terrain surface. A triangular surface mesh representative of an existing surface is obtained and consists of triangles that are connected by vertices and edges. A drain intention is specified for the terrain surface through a geometry that is a point or line. The drain intention defines a drainage flow that influences a shape of the terrain surface. The mesh is modified to prevent a drain conflict between mesh triangles. A drain direction is autonomously determined for each of the mesh triangles based on the drain intention. The determination generates a drain pattern that is used to shape the terrain surface.
