Abstract: A distributed animation comprising a plurality of processors wherein each processor is responsible for rendering only a portion of the entire image. After the plurality of processors compute their respective images, the image data is communicated to a buffer. The buffer also receives image data from other sources. The buffer combines the image data from all sources into a single image frame which is then stored in a frame buffer. The buffer comprises a plurality of buffer elements, each buffer element being associated with a single graphics element (processor or video source). Each buffer element includes an input terminal for receiving pixel data from its corresponding graphics element, an output terminal for outputting pixel data, and a second input terminal for receiving pixel data from the output terminal of a previous buffer element. The pixel data typically includes a Z value which provides the depth location in the image of the object represented by that pixel.

Abstract: An interactive method of communicating with a language deficient user such as an aphasic patient is disclosed. The computer has a display with a pointing device for visually indicating a position through a cursor means on the display. In one example, a plurality of images with each image being a graphical representation of word oriented information or a component thereof is displayed. A plurality of tool-like icons is also displayed. The cursor can be positioned to one of the desired plurality of tool-like icons. When one of the plurality of tool-like icons is selected by the user, the cursor is changed into the image of the tool-like icon selected. The tool-like icon image selected for the cursor is then moved to one of a plurality of the images which represent word-oriented information or a component thereof. When the cursor is activated on the image, a display of information represented by the tool-like icon acting on the word-oriented image is then visually displayed by the computer.
