Texture gradients are said to provide information for depth perception because elements in a scene become more densely packed as distance increases. The examples of texture gradients in Figures 10.6 and 10.8 contain regularly spaced elements that extend over large distances. But regularly spaced elem

Disney Transit Consider the chapter-opening quote. Suppose your citys transportation manager hires the team of workers that designed the most popular Disneyland rides and asks them to redesign the citys transit system. The citys objective is to increase ridership while eliminating the transit subsidy
