HARDWARE FOR COMPUTER GRAPHICS

*Notable Graphics Workstations and Graphics Hardware:

Graphics performance is difficult to measure because of the widely varying complexity of visual scenes and the different hardware and software approaches to computing and displaying visual imagery

*Graphics Architectures for VE Rendering: This section describes the high-level computer architecture issues that determine the applicability of a graphics system to VE rendering. Two assumptions are made about the systems included in our discussion. First, they use a z-buffer (or depth buffer), for hidden surface elimination. A z-buffer stores the depth—or distance from the eye point—of the closest surface ''seen" at that pixel. When a new surface is scan converted, the depth at each pixel is computed. If the new depth at a given pixel is closer to the eye point than the depth currently stored in the z-buffer at that pixel, then the new depth and intensity information are written into both the z-buffer and the frame buffer

*Computation and Data Management Issues in Visual Scene Generation:

Many important applications of VE require extensive computational and data management capabilities. The computations and data in the application primarily support the tasks taking place in the application. For example, in simulation, the computations may support the physical behavior of objects in the VE, while in a visualization application the computations may support the extraction of interesting features from a complex precomputed dataset. Such computations may require on the order of millions of floating point operations.

*Graphics Capabilities in PC-Based VE Systems: Small VE systems have been successfully built around high-end personal computers (PCs) with special-purpose graphics boards
