Top-left:
Anders Hast - A new function for specular highlights makes it possible to change the size of the highlight linearly and it is easy to create arbitrary small sizes, which was not practically possible with the power function used in the Phong specular highlight model.

Top-right:
Xavier Tizon - Composite rendering of an abdominal MRA subvolume. The arterial centerlines are displayed as small spheres at each voxel location, colored with the curvature value at each voxel. Curvature measures how much the vessel locally deviates from a straight line.

Bottom-left:
Felix Wehrman - The picture shows the regular sampling of two-dimensional shapes and scenes. Subject to variation, such an object resides on a low-dimensional, nonlinear manifold in the hyperspace of measurements.

Mats Erikson - Aerial image and its segmentation into individual tree crowns.
