1 INTRODUCTION
Computer graphics hardware has been rapidly increasing in per- formance. This has motivated immediate-mode graphics inter- faces like OpenGL [20] to adopt constructs such as display lists and packed vertex arrays in order to alleviate system bottlenecks. However, these constructs may impose an undesired paradigm shift for the application programmer, and they may not be useful in resolving the particular performance bottleneck. Furthermore, with the increasing use of multiprocessor systems for graphics applications, a serial interface to the graphics system can be inelegant. A parallel graphics interface seeks to resolve these issues. To provide a common framework, we first review three key issues in graphics interfaces.
The first issue in designing a graphics interface is state. In a stateless interface, the behavior of every command is independent of every other command; thus, every command must include all the information required to execute that command. Conversely, in an interface with state, a command’s behavior can be affected by previous commands. Some of the information required for the execution of commands may reside within the state maintained by the interface, and some commands modify that state.
