    • Methods and systems to determine view cell occlusion, including to project objects of a 3-dimensional graphics environment to a 2-dimensional image plane with respect to the view point, to reduce sizes of corresponding object images, to generate an occluder map from the reduced-size object images, to compare at least a portion of the object images to the occluder map, and to identify an object as occluded with respect to the view cell when pixel depth values of the object image are greater than corresponding pixel depth values of the occluder map. Methods and systems to reduce an object image size include methods and systems to nullify pixel depth values within a radius of an edge pixel, and to determine the radius as a distance from the edge pixel to a second pixel so that a line between the view point and the second pixel is parallel with one or more of a line and a plane that is tangential to a sphere enclosing the view cell and a point on the object that corresponds to the edge pixel.
    • 确定观察细胞闭塞的方法和系统,包括将三维图形环境的对象相对于视点投影到二维图像平面,以减小相应对象图像的大小,从缩小的图像生成闭塞图 将对象图像的尺寸调整为将至少一部分对象图像与遮挡物图进行比较,并且当对象图像的像素深度值大于对象图像的对应像素深度值时,识别相对于视图单元被遮挡的对象 封堵器图。 减少对象图像尺寸的方法和系统包括使边缘像素的半径内的像素深度值无效的方法和系统,并且将半径确定为距离边缘像素到第二像素的距离,使得视点 并且第二像素平行于与包围视图单元的球体相切的线和平面以及与边缘像素对应的物体上的点的一个或多个。

    • An apparatus and method are provided for two-channel bidirectional communications between devices for enhanced data signals. In particular, the techniques describe a first transceiver channel configured to receive first data communications from a first transceiver port. A second transceiver channel is also configured to receive second data communications from a second transceiver port. A set of signal pins are configured to receive the first data communications from the first transceiver port at a first group of signal pins and to receive the second data communications from the second transceiver port at a second group of signal pins. The first group of signal pins comprises signal pins in a signal-signal-ground configuration and the second group of signal pins comprises signal pins in a ground-signal-signal-ground configuration.
    • 提供了用于增强数据信号的装置之间的双通道双向通信的装置和方法。 特别地,这些技术描述了配置成从第一收发器端口接收第一数据通信的第一收发器通道。 第二收发器通道还被配置为从第二收发器端口接收第二数据通信。 一组信号引脚被配置为在第一组信号引脚处从第一收发器端口接收第一数据通信,并且在第二组信号引脚处接收来自第二收发器端口的第二数据通信。 第一组信号引脚包括信号 - 信号 - 接地配置中的信号引脚,第二组信号引脚包括接地信号 - 接地配置中的信号引脚。
