Abstract:
1. A method for synchronous representation of a terrain—formed from polygons—of a virtual reality on a plurality of display devices of a simulation device, which has a plurality of simulation computers connected to one another via a network, wherein spatial coordinates of the polygons of the terrain are stored in each simulation computer and wherein a first simulation computer generates a change of the terrain, the method comprising: generating position data specifying which region of the terrain was changed by a first one of the plurality of simulation computers; generating elevation data of the changed region of the terrain by the first one of the plurality of simulation computers; communicating the position data and the elevation data via the network by the first one of the plurality of simulation computers to a second one of the plurality of simulation computers; selecting, on the basis of the position data, those polygons of the terrain which lie in the changed region by a control unit of the second one of the plurality of simulation computers; subdividing the selected polygons in each case into a plurality of sub-polygons by a tessellator unit of the second one of the plurality of simulation computers; calculating spatial coordinates of the sub-polygons in accordance with the elevation data by a calculation unit of the second one of the plurality of simulation computers; and displaying the sub-polygons on a display device connected to the second one of the plurality of simulation computers.
