    • A method, apparatus, media and signals for generating a computer representation of a three-dimensional swept envelope of a vehicle having a wheeled chassis operable to support a vehicle body for movement along a terrain is disclosed. The method involves receiving terrain data representing a 3D terrain, receiving data defining parameters of the vehicle, and receiving data defining a path for movement of the vehicle from an initial position on the terrain to a displaced position on the terrain. The method also involves disposing a computer representation of the vehicle on the 3D representation of the terrain at successive locations along the path using the parameters. Disposing involves determining points of engagement between wheels of the wheeled chassis and the 3D representation of the terrain to dispose the chassis with respect to the terrain, and determining a corresponding 3D location of the vehicle body with respect to the terrain. The method further involves generating a plurality of spatial extents of the vehicle at the successive locations, the spatial extents defining the 3D swept envelope of the vehicle when moving between the initial position and the displaced position. In another aspect a method for generating a computer representation of a three-dimensional swept envelope of an object moving along a guideway disposed with respect to a 3D representation of a terrain is disclosed.
    • 公开了一种用于产生具有可操作以支撑车身沿着地形运动的轮式底盘的车辆的三维扫掠包络的计算机表示的方法,装置,介质和信号。 该方法包括接收表示3D地形的地形数据,接收定义车辆参数的数据,以及接收定义用于使车辆从地形上的初始位置移动到地形上的位移位置的路径的数据。 该方法还涉及使用参数在路径的连续位置处将车辆的计算机表示设置在地形的3D表示上。 处置涉及确定轮式底盘的车轮与地形的3D表示之间的接合点,以相对于地形布置底盘,以及相对于地形确定车体的对应3D位置。 该方法还包括在连续位置处产生车辆的多个空间范围,当在初始位置和位移位置之间移动时,空间范围限定车辆的3D扫描包络线。 在另一方面,公开了一种用于生成沿着相对于地形的3D表示布置的导轨移动的物体的三维扫描包络的计算机表示的方法。

    • A method and apparatus for displaying a representation of a traffic intersection on a display of a computer is disclosed. The method involves receiving operator input defining a relative orientation between a first roadway and a second roadway, the first and second roadways forming an intersection area therebetween. The method also involves receiving an operator selection of a design vehicle that is expected to use the traffic intersection, the design vehicle being defined by a plurality of design vehicle parameters. The method further involves generating at least one turning path of the design vehicle through the intersection between the first roadway and the second roadway, and generating first vehicle extent locations associated with passage of the design vehicle along the at least one turning path. The method also involves generating an outer edge of the intersection area, the outer edge being generally aligned with selected ones of the first vehicle extent locations, and generating display signals for causing the computer display to display an image representing the traffic intersection.
    • 公开了一种用于在计算机的显示器上显示交通路口的表示的方法和装置。 所述方法包括接收限定第一道路和第二道路之间的相对定向的操作者输入,所述第一和第二道路在其间形成交叉区域。 该方法还包括接收对期望使用交通路口的设计车辆的操作员选择,设计车辆由多个设计车辆参数定义。 该方法还包括通过第一道路和第二道路之间的交叉点产生设计车辆的至少一个转动路径,以及生成与设计车辆沿着至少一个转向路径通过相关联的第一车辆档位位置。 该方法还包括产生交叉区域的外边缘,外边缘与第一车辆档位位置中的所选择的一般大致对齐,并且产生用于使计算机显示器显示表示交通路口的图像的显示信号。
