    摘要： A computer generates one or more geometric rays at a predetermined height above one or more portions of an avatar's body in a virtual environment. Once the rays are generated, the computer computes intersections of the one or more rays with a collision mesh that defines a terrain of the virtual environment at the location of the avatar. Then, the computer computes the point of intersection of each of the one or more rays with the collision mesh. Using the points of intersection, the computer calculates an offset in an elevation and/or an offset in an orientation of the avatar with respect to the terrain in the virtual environment. Further, the computer adjusts the elevation and/or the orientation of the avatar based on the calculated offset in the elevation and/or the elevation in the orientation, respectively, such that the adjusted elevation and/or orientation compensates for the calculated offsets.

    摘要翻译： 计算机在虚拟环境中在化身的身体的一个或多个部分上方的预定高度生成一个或多个几何线。 一旦产生了光线，计算机就会计算一个或多个光线与碰撞网格的交点，碰撞网格定义了化身所在位置的虚拟环境的地形。 然后，计算机计算每个一个或多个射线与碰撞网格的交点。 使用交叉点，计算机在虚拟环境中计算化身的方向上的高程偏移和/或偏移量相对于地形。 此外，计算机分别基于计算出的仰角和/或仰角的偏移来调整化身的仰角和/或姿态，使得调节的仰角和/或取向补偿所计算的偏移。

    摘要： A computer determines a modified location for an avatar of a first entity in a virtual environment based on a location of the first entity in a capture volume and a transformation used to map a second entity from the capture volume to the virtual environment. The modified location of the avatar of the first entity relative to a location of an avatar of the second entity is consistent with the location of the first entity relative to the location of the second entity in the capture volume. Once the modified location is determined, the computer displays a graphical cue corresponding to the first entity at the modified location of the avatar of the first entity provided that a distance between the modified location of the avatar of the first entity is different from a current location of the avatar of the first entity in the virtual environment.
