Modeling objects and environments

摘要: McIntosh, in ACADIA Newsletter Vol. 9 No. 3 pp 20-23, June 1990. This book introduces the concept of modeling objects computer's memory so it can be used to aide process their design. Modeling is defined as an hierarchical abstraction data and operators manipulate it, subject semantic integrity constraints that guarantee realizability designed artifact real world. Starting with general concepts modeling, moves on discuss shapes (form) two three dimensions. The discussion covers both topology geometry. Next shape transformations (translation, scaling, rotation, etc.), absolute relative terms. then assembly adds non-graphical attributes representation. It concludes a user interface parametrization. includes many examples written Pascal complement theory, basis for building geometric engine. also exercises, text two-semester advance course
