Caption

This video shows the sole of a shoe as it appears from different perspectives in rendering software. The shoe was placed upside down on an optical table (seen as flat surface with regularly spaced holes). The colors indicate distance, with blue/purple indicating shorter distances (or higher areas of the shoe sole) and red/brown longer distances. In the second part of the movie detailing the shoe sole pattern, the color scale spans a range of about 10 millimeters (mm). The prominent shoe sole patterns are about 1-2 mm deep.
