Object-oriented view coordinate space system

摘要

A view system provides support for applying matrix operations to one or more views to render a view in a more realistic manner. The matrix operations are applied in accordance with a predefined coordinate system for each application to generate the screen information for each application program. The view system applies the matrix operations to generate views appearing on the display, off the display and partially on and partially off the display. Furthermore, the system enables hierarchical linkage of views to enhance the correspondence between a view undergoing a transformation and proximal views.
