Abstract: Methods, devices, systems, and computer readable media to improve the operation of window-based operating systems is disclosed. In general, techniques are disclosed for correctly rendering areas on a display in which two or more shadows overlap. More particularly, two or more shadow regions (based on the arrangement of overlapping windows/shadows) are identified and merged in a top-down process so that no region's shadow is painted or rendered more than once. To accomplish this a shadowbuffer (analogous to a system's framebuffer) may be used to retain windows' alpha information separately from the corresponding windows' shadow intensity information.

Abstract: An operating system creates one or more virtual display interfaces for communication of display data and user input events between the application layer and one or more virtual display devices. The one or more virtual display devices are not physically connected to the computing system managed by the operating system. One or more applications are executed in an application layer. At least one of the one or more applications communicates display data to and receives user input events from at least one of the one or more display devices using at least one of the display interfaces. At least one other of the one or more applications communicates display data to and receives user input events from at least one of the one or more virtual display devices using at least one of the one or more virtual display interfaces.

Abstract translation: 公开了用于改进基于窗口的操作系统的操作的方法，设备，系统和计算机可读介质。 通常，公开了用于在其中两个或更多个阴影重叠的显示器上正确渲染区域的技术。 更具体地，两个或更多个阴影区域（基于重叠的窗口/阴影的布置）被识别并在自上而下的过程中合并，使得不区域的阴影被绘制或渲染不止一次。 为了实现这一点，可以使用shadowbuffer（类似于系统的帧缓冲区）来保持窗口的alpha信息与对应的窗口的阴影强度信息分开。
