The SIGGRAPH ’84 technical slide set represents the state-of-the-art in computer graphics. The set is an example of over 800 slide submissions from industry, academia and the art world. All images are marked with a proper copyright notice and are not to be further copied or reproduced without the explicit permission of the individual copyright owners. Each slide is printed here in black and white to facilitate locating information about the images. The full color 35mm slide set can be ordered from ACM. See the listing above of SIGGRAPH ’84 materials available.
Ned Greene, NY.IT Computer Graphics Lab, Box 170, Old Westbury, NY 11568, (516) 686-7644. “Inside a Quark.” All objects in the scene were modeled in three dimensions from polygons. The vines were modeled using tree modeling software authored by Jules Bloomenthal and rendered with bump mapping. A depth image for the bark texture was obtained by x-raying a plaster cast of real bark. Flowers, sepals, and leaves were modeled using a program which creates a polygon mesh file from a depth image and hand-drawn boundary curves. The leaves and sepals were texture mapped with painted texture. Depth cueing simul;ites homogenous fog; contrast falls off as an exponential function of distance from the eye. Design, modeling, and animation by Ned Greene. The hardware used was a DEC VAX 11/780 computer with Genisco frame buffers. Software credits to Jules Bloomenthal, Paul Heckbert, Ned Greene, Lance Williams.
