<p>[QUOTE=&quot;messydesk, post: 2676287, member: 1765&quot;]Glad you like the GIF!&nbsp; I&#039;m pretty happy with the way it turned out.&nbsp; I had to rehearse the lighting path a couple times.&nbsp; The section of the hologram that shows up and its color are a function of not only the position of the light around the coin, but also the height of the light.&nbsp; The magnitude of first derivative of the color (itself a vector) with respect to the lighting vector tends to be either large or zero (i.e., the color is either volatile or not there at all), so I needed to use 15 pictures instead of the usual 6 to capture any sense of a gradual change.[/QUOTE]</p><p><br /></p>
