A Useful Illustion from the Exploratorium ~ Monday, August 20, 2012
We visited the Exploratorium last weekend. This was Nate's first visit, and he really liked it.
The museum has many exhibits demonstrating aspects of human senses, including a bunch that demonstrate optical illusions. Take a look a this column, for example.
Looks fluted, doesn't it?
Have a closer look:
The stripes are actually solid shades of gray--it's just the contrast with adjacent lighter and darker shades that creates the illusion of a gradient, suggesting shading from a concave contour.
That could be a useful trick in modelling--custom print a wraparound decal with gray stripes, apply it to a plain piece of styrene rod, and instantly you've got a believable fluted column for your neoclassical town hall, Carnegie library, etc...
