ANIMATION DISPLAY WORK STATION

摘要

PURPOSE:To realize the video animation with realtime special effect on the work station operating under the non-realtime OS on a multi-window. CONSTITUTION:The video animation on a plane 1 and the graphic drawing on a plane 2 are selectively displayed by a key plane. The key plane is divided into a window area plane 3 representing the area of the window which belongs to the video animation and updated when a window state has a change and an animation display effective area plane 4 purely representing the effective area of the video animation to be updated in real time regardless of the window fluctuation, and the logical AND areas of the 3 and 4 are used as key information. Thus, even in the work station of the non-realtime OS, the animation with the extremely smooth realtime special effect can be realized on the multi- window, and the superior value for the application of multi-media is displayed.
