CS 348B 1993 Rendering Competition
CS 348B - Computer Graphics: Image Synthesis Techniques
Winter quarter, 1993
Instructor: Marc Levoy
Teaching assistant: Daniel Goldman
Press here for a general introduction to these
Chase's winning entry from the Winter of '93 features dimpled oranges
and smoke rising from a coffee cup. Both of these objects, as well
as the distorted globe in the background, were rendered using Chase's
volume raytracer. The orange's skin and the distorted globe are
isosurfaces of a volume density function, while the smoke is directly
rendered from another density function.
Golf Ball, by Jim Christy
Jim's golf ball was not only texture mapped with a genuine Spalding
golf ball label; it was also bump-mapped with several hundred dimples,
placed at the centers of triangles generated by a regular tessellation
of the sphere.
Grand Scene, by Bruce Romney and Mike Smith
Bruce and Mike's scene exhibits almost all of the major functionality
required in the course project. Note that while the top mirror is
shiny, the lower one is diffuse. Also, the shadow cast by the blue
cube is diffuse. Both of these are created by distribution
ray-tracing. Other features include refraction and texture mapping.
Intel Mug, by John Heinlein and Steve Farris
John and Steve's image was designed to match a real-life scene, which
they showed alongside their computer-generated image. Although
difficult to see at this resolution, the mug's surface has several
scratches and other markings, as did the real object.
Marble Vase, by Patrick Teo
Patrick's elegant marble texture won him an honorable mention in the
render-off. His renderer utilized a very efficient space-subdivision
method coupled with a progressive refinement technique which allowed
the user to watch the image slowly appear as it was calculated.
