    • A method for synchronous representation of a virtual reality terrain in the form of polygons on a plurality of display devices by a plurality of connected simulation computers, may include generating position data specifying which region of the terrain was changed by a first computer; generating elevation data of the changed region by the computer; communicating position and elevation data the first computer to a second computer; 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 computer; subdividing the selected polygons in each case into a plurality of sub-polygons by a tessellator unit of the second computer; calculating spatial coordinates of the sub-polygons in accordance with the elevation data by the second computer; and displaying the sub-polygons on a display device connected to the second computer.
    • 用于通过多个连接的模拟计算机在多个显示设备上以多边形形式同步表示虚拟现实地形的方法可以包括产生指定地形的哪个区域被第一计算机改变的位置数据; 通过计算机生成改变区域的高程数据; 将第一计算机的位置和高程数据传送到第二计算机; 基于所述位置数据,通过所述第二计算机的控制单元来选择位于所述变化区域中的所述地形的所述多边形; 通过第二计算机的细分器单元将所选择的多边形细分为多个子多边形; 根据第二计算机的高程数据计算子多边形的空间坐标; 以及在连接到第二计算机的显示设备上显示子多边形。
