Fractal surfaces have recently been shown to be a useful model for generating images of terrain in computer graphicS. Unfortunately, the generation of fractal images is very costly in CPU time. A multiprocessor architecture is described which takes advantage of the parallelism inherent in fractals to speed the generation of images. The performance of the processing array is analyzed along with the suitability of implementation in VLSI.

There exists a widely held belief that the full potential of LSI technology will be realized by arrays of logic circuits. A novel machine architecture is proposed that consists of a uniform array of identical cells with the property that the array executes a high-level programming language directly. Some of the more important features of such machines are their inherent abilities to sustain concurrent processes and to maintain efficient information storage. A detailed simulation of a language machine in its architectural style is presented.

The availability of inexpensive minicomputers and low cost digital/ analog conversion equipment enables one to use interactive graphics in situations where such techniques were previously infeasible. The University of Tulsa is presently developing an interactive graphics package entitled BANDMARCH to assist the choreography of marching band drills. The graphics hardware consist of a 32K Interdata Model 70 minicomputer, a 5MB Diablo Disc system, a Tektronix 603 monitor with 256 x 256 point display provided by a pair of Datel 8 bit D/A converters. The program enables a band director who is most likely not computer oriented to prepare a routine in an existing language (About Face, Left Flank) and view the result of his "design" in realtime. The obvious interactive features of editing, cataloguing and accessing standard functions must be provided in a way that can be easily understood.T. U.'s BANDMARCH (not an acronym) provides such features. Common data structures in a relatively novel environment are a demonstration of the soundness of these techniques to an interactive graphics situation.
