Abstract
Current graphics processors are very slow for displaying shaded 3D objects. A lot of work is being done in order to define faster display processors by using massive parallelism and VLSI components. Our proposal goes along this line with the supplemen tary aim of displaying images in real time, i.e., 25 or 30 times per second. We choose to design a graphics module without any working memory and thus without frame buffer. A massive parallelism over objects, and thus a pixel pipe-line, are used. Each Object Pro cessor handles one 3D object; all the processors work in a synchronous way, processing the same pixel simultaneously at pixel rate. These processors are built from very simple Elementary Processors (2 adders, 2 registers and 6 memory words) computing linear or quadratic expressions V(x,y), where (x,y) are the coordinates of a pixeL A pipelined tree made of basic operators (min, max, or, and, ... ) gathers the results given by the Ob ject Processors and makes inter-objects operations, at least hidden part elimination. Such a choice of course involves a high hardware complexity when displaying rather sim ple scenes. However, we feel that it is the price to pay for building graphics processors allowing real-time interactive animation (e.g., the graphics unit of a driving simulator).
