It shows a human figure with 12 segments and 36 degrees of freedom. The body is internally represented as a tree structure of segments and intervening joints. By sending positions to the joints, a particular spatial configuration is achieved. Associated with each segment is a max-min box representing its extent in space. The Ribbon Man image is developed by associating a helix with each max-min box, and rendering the helices as sequences of thin triangles. The background was painted using “Blot,” an experimental “paint program” developed at the Berkeley Computer Graphics Laboratory for the creation and testing of color and paint algorithms.?

    34. ANDY MORFFEW, IBM united Kingdom Limited, P.O. Box 32, Alencon Link, Basingstoke, Hampshire R62 i I EJ England; (0256) 56144. “Will.”?
    35. BEN TRUMBORE, KELAN PUTBRESE, Brown University, Box 1910, Providence, RI 029 I 2 and Rhode Island School of Design, (401) 863-3666. “Afternoon at the Club.” An in-house, high level scene description language was used exclusively to model this image on a VAX 11/780 running 4.2 BSD UNIX. Recording device is a Matrix Instruments QCR D-4/2. All local modeling, rendering and animation software is based on this scene description language. Programmers are: Paul Strauss, David Laidlaw, Michael Shantzis, Jeff Vroom and John Airey.?
    36. DON VENHAUS Pacific Data Images, 111 I Karlstad Drive, Sunnyvale, CA 94089; (408) 745-6755. “Chromosaurus.” The image was designed and rendered on Ridge 32C computers using a Raster Technologies frame buffer.?
    37. PETER WATTERBERG, Sandia National Laboratories, 335 Broad St. A-5, Augusta, GA 3090 I; (404) 724-0795. “Tahoe Afternoon.” Experimental ray tracing software was used to render fractal mountains, clouds and ripples. The image was recorded on a Dicomed D48C at l 800x 1200 resolution. The clouds and terrain used the same data-base created from algorithms by Richard Voss.?
    38. JERRY WEIL, AT&T Bell Laboratories, 600 Mountain Avenue, Murray Hill, NJ 07974; (20 I) 582-7833. “Bathroom Sequence.” The image was created on a user-friendly animation system with an iconic interface. The artist is Jerry Weil; programmers are Jerry Weil and Jonathan Helfman.?
    39. C. WILLIAMSON,Candle Corp., 1355 N. Gardner, Los Angeles, CA, 90046; (213) 8507777. “Chicago.” Equipment used was the MCI Quante! paint box.?
    40. STEPHEN WOLFRAM, The Institute for Advanced Study, Princeton, NJ 08540; (609) 734-8000. This image arose from modeling various complex physical phenomena. It illustrates the mathematical principle that complexity can be generated even when the components of a system are quite simple. Further background on this image can be found in my article in the September 1984 issue of Scient(ftc American, in Nature, volume 311, page 419.?
    41. BRIAN WYVILL, University of Calgary, Department of Computer Science, 2500 University Drive NW, Calgary T2NIN2 Alberta, Canada, (403) 284-6009. The Graphics land Animation system was used where objects have been composed of multiple typed primitives. The fractal mountains, particle grass, particle leaves, and polygonal trees are rendered in a single pass.
    42. MAU.REEN STONE, ERIC BIER, Xerox Corporation, Xerox PARC, 3333 Coyote Hill Rd., Palo Alto, CA 94304; ( 415) 494-4849. “The t Doctor’s Table.” The image was designed using an interactive, three dimensional illustration program called “Solidviews.” Solid views implements a constructive solid geometry system with pattern mapping. The slide is a photograph of a hardcopy produced on the Versatec color plotter.?
    43. LESLIE A. DREILING, U.S. Government, 738 Ridge Dr., Mclean, VA 22101; (703) 351-6553. “Feeding Fish.” This self-squared “z-plane” fractal was created with a FORTRAN program developed by the submitter. An IBM 3083 was used for calculation, which took 5 hours. Calculations were made on a point by point basis for the 4000 line resolution image. ISSCO’s DISSPLA graphics software was used to generate the image on a Dicomed D l 48CR film recorder in vector mode. Approximately a quarter of a million points on the complex plane were iteratively calculated using the equation z = wz (1-z), where w = 1.00155 i 0.0627 and z = X + iy.?
    44. PETER QUARENDON, STEPHEN TODD, IBM United Kingdom, Scientific Centre, Athelstaw House, St. Clement St., Winchester, HMNTS, UK, S0239DR, (0962) 68 I 9 I. “Fisheye.” View from the center of pre-albumin using a fisheye lens.
