Flexibility in an Object-Oriented Graphics Kernel by Overriding Internal Methods

摘要

The requirements to achieve a flexible graphics kernel are discussed. It is shownthat an object-oriented approach can lead to a system that can be customized to various needs of applications without giving up the idea of a hidden internal implementation. The basic principles are discussed alongside an example where the application is a small graphics editor and the kernel is a multi-level graphics system. Implications on future object-oriented graphics standards are mentioned. (Copyright (c) GMD 1991.)
