Cool painting tech demo o’ the day
Photoshop engineer Jerry Harris is responsible for the application’s painting tools, and he’s always got an eye open for interesting developments in the field of computerized painting. This morning he passed along a cool demo video of James McCann and Nancy Pollard’s Real-time Gradient-domain Painting technology.
In a nutshell, according to the video, "A gradient brush allows me to paint with intensity differences. When I draw a stroke, I am specifying that one side is lighter than the other." Uh, okay… And the video is a little ho-hum until the middle. That’s when things get rather cool. Check out cloning/duplicating pixels along a path, plus the interesting approach to painting a band of color.
