Fun programming 148: Drawing shapes with glow or shadow
By drawing the stroke of a shape multiple times with low opacity we can easily achieve glows and shadows. A simple concept that can produce good looking images. Here some examples: hamoid.tumblr.com/post/76579918775/84932-jpg-34758-jpg-and-49862-jpg-as-saved-by (expired link)
Tip: the darkness of the shadow or glow should not decrease in a linear fashion (like 8, 6, 4, 2) or it will not look too real. That's why I used distances like 22, 33, 44 and 55. I'll try to record an episode in the future about linear vs exponential and other interesting curves. Meanwhile here you can find information about curves at: robertpenner.com/easing/
