Search Results for "cast"

...Suitable for study in academic institutions, especially as related to line-drawing accuracy. Particular attention to detail concerning chopping of accumulation errors, using a cast from 64 bit to 32 bit strategy, in the interval [1.0,2.0). Individual pixel errors with overlapping polygons or line segments are about one in a billion, but I can't reproduce any errors at the moment by using random number generation with tens of millions of cases. Emphasis not only on correctness, but also on performance for real-world use or hardware implementation.

...First the image is broken down into planes. Each plane is given a depth distance. The image belonging to each plane is horizontally compressed enough that the "shadows" cast by the image belonging to the planes in front of it cover the "holes" in the plane. The whole thing is then animated in a gentle see-saw fashion to get the wiggle effect. Wiggle Stereography was invented by Jim Gasperini, who made them by hand.
