    1 . PETER WATTERBERG, 2644 Sandia National Laboratories, Albuquerque, NM 87185, (505) 844-7196. “SIGGRAPH ’83/Mandrill Title Slide”. The image was generated at a resolution of 819 x 518 using a ray tracing algorithm employing color mapping and texture techniques developed by Jim Blinn. Software was written by Peter Watterberg. Hardware includes a VAX 11/780, Cray-lS, Cyber 76 and Dicomed D48 film recorder.

    2 ROB COOK (director), Lucasfilm Ltd., P.O. Box 2009, San Rafael, CA 94912, (415) 499-0239. “Road to Point Reyes”. This landscape was defined using patches, polygons, fractals, particle systems, and a variety of procedural models. The various elements were rendered separately and later composited. Rob Cook designed the picture and did the texturing and shading, including the road, hills, fence, rainbow, shadows and reflections. Loren Carpenter used fractals for the mountains, rock and lake, and a special atmosphere program for the sky and haze. Tom Porter provided the procedurally drawn texture for the hills and wrote the compositing software. Bill Reeves used his particle systems for the grass and wrote the modeling software. David Salesin put the ripples in the puddles. Alvy Ray Smith rendered the forsythia plants using a procedural model. The visible surface software was written by Loren Carpenter, and the anti-aliasing soft- ware by Rob Cook. The picture was rendered using an lkonas graphics processor and frame buffers, and was scanned on a COLOR FIRE 240, courtesy of MacDonald Dettwiler and Associates Ltd. The resolution is 4K x 4K, 24 bits/pixel.

The image was generated using a ray tracing algorithm Enderle designed and integrated in GIPSY, a 3-D graphics system originally developed by Richard Schuster of BMW, Munich. The objects, part of the Tandem Mirror Fusion Reactor T ASKA, were modeled with GIPSY by E.G. Schlechtendahl .and K.H. Bechler. The image was produced on an AED 512 color raster tenninal connected to an IBM main- frame. The original hardcopy was generated by a Matrix 4000 color camera system on Ektachrome film.
