coin tricks

These are experiments, shown as a proof of concept rather than as finished, fully-retouched productions.

My decisions regarding lighting are arbitrary. I wanted the turning object to look like it’s in a real environment, where the surface reflects differently at different angles. Some coin animations on the web use straight-on shots of the obverse and reverse and distort them to simulate rotation; it’s much easier to do, but it looks as fake as it is.

Note that spinning a coin shows one of its two faces upside-down relative to the other. Flipping shows both faces oriented correctly.

These coins were shot at about 2500 pixels in diameter and reduced by quite a bit for the animations, to keep the file sizes reasonable for web pages. I used 24 frames (15-degree increments) for three of these, and 18 frames (20-degree increments) for one. You’ll also see that I set different transition speeds on them, which can be easily modified.  I’ve tried two output formats — GIF and MP4 — but that’s a complex issue. I think the web developers would have to make the final decisions on that.
