The Computer Graphics Forum 2004 Cover Image has been selected by the CGF editorial board. We thanks all people who submitted this year, and hope that they will participate to the next year contest.

Winner of the Computer Graphics Forum 2004 Cover Image Contest

The image has been rendered by my Monte-Carlo renderer that used a modified Metropolis Light Transport (MLT) algorithm. The rendered scene includes a pair of big gold spheres and blue metalic cones and many little silver balls floating in the air and it is illuminated by large studio light. I believe that only the most ambitous and exact algorithms like MLT can render sense of real space

Second place:

The image was created using Twister (Twister A Space-Warp Operator for the Two-Handed Editing of 3D Shapes, by Llamas, Kim, Gargus, Rossignac and Shaw, Proc. of ACM SIGGRAPH 2003). I created this model starting with a box, then stretched it and twisted it with my hands, by means of magnetic trackers with buttons attached to them. As an anecdote, this model was created during a visit of Fred Brooks to our lab, the VWLAB at Georgia Tech. The image is simply rendered using OpenGL and spherical environment mapping using a picture of Mars taken by the Viking 1 lander. The environment map is all but correct but it does the trick.

Human liver vessels exhibit sophisticated patterns of interaction and are crucial for the planning of liver transplant and resection surgery. Three vessel systems have been generated under the constraint of intravascular volume minimization, and rendered in grey for the shapes of a square, a disc, and a human liver. Shown in red and blue are the actual portal and hepatic veins of an individual human liver based on a computer tomographic image of a corrosion cast.
