When Curious George's new bath toys go down the drain, it's time to call the plumber. With some amazing tools (and George's help), the toys are found and the pipes are cleared. When a second drain disaster occurs, George tries fixing it on his own, "without "the same success. Ultimately, George learns that the best way to keep the plumbing system working is to prevent clogs in the first place . . . "and "to invest in extra large (and extra fun) bath toys. George's latest adventure includes fun facts about how water gets to your house along with a coloring and tool-labeling activity.
Computer graphics, computer-aided design, and computer-aided manufacturing are tools that have become indispensable to a wide array of activities in contemporary society. Euclidean processing provides the basis for these computer-aided design systems although it contains elements that inevitably lead to an inaccurate, non-robust, and complex system. The primary cause of the deficiencies of Euclidean processing is the division operation, which becomes necessary if an n-space problem is to be processed in n-space. The difficulties that accompany the division operation may be avoided if processing is conducted entirely in (n+1)-space. The paradigm attained through the logical extension of this approach, totally four-dimensional processing, is the subject of this book. This book offers a new system of geometric processing techniques that attain accurate, robust, and compact computations, and allow the construction of a systematically structured CAD system.
