Raytraced range maps

Data

This a 3-D range map captured by a single-plane structured light sensor.

The vintage of the computer hardware suggests how old this is.

Method

Raw sensor data converted to range map by eod-to-xyz.
Range map downsampled by 2x and tesselated by xyz-to-pov.
Eyepoint 85 mm from centroid, rotated in x-z plane in 2-degree steps.
33,664 triangular facets raytraced by POV-Ray. 45 frames, each 480x360 pixels, raytraced in 9510.95 CPU seconds on a 486DX2-66 (avg of 211.34 seconds/frame).
Years later, assembled into an MPEG video file using ImageMagick's convert program.
