The images below were prepared for the IRTC (International
RayTracing Competition) in Oct/2009. They weren't accepted because
competition server was overloaded and I couldn't get them in before
closing time (It wasn't for lack of trying). Anyway, I put in
enough work, and the result wasn't that bad, so here they are.
Slightly closer to the first digit.
Detals of the first digit.
The 7 segment decoder.
Details of segment D mechanicals
Detail of segment G's setup. The wavy surface right is the
reverse side of the front plate.
Steam pipes for the pistons, and the axis of one of the segments.
The blue cylinder is one of the pistons.
Two of the segments - the nearest one 'off', the other 'on'.
