- Page 2 HP set the standard for performance and functionality for the Microsoft Windows NT-based technical workstations when it introduced systems with VISUALIZE-fx4 graphics for Windows NT in 1997. In 1998, HP raised the bar with the VISUALIZE-fx6+, designed specifically for optimal performance in Intel/Microsoft based systems. Now, HP has broadened the offerings with a family of products for NT with the VISUALIZE-fx4+ and soon the VISUALIZE-fx2+.

- Page 5 graphics throughput for display lists is almost always higher. Display lists are very effective when the same data is to be displayed multiple times. Good examples are an architectural walk-through of a building or a fly-through of a complex mechanical assembly. Nevertheless, there are compelling reasons for some applications to use immediate mode.
- Page 6 In Figure 3, the power of the fx6+ is evident, showing the ability to achieve over 5.5 Million triangles per second by using OpenGL's triangle strip primitive. The fx4+ achieves 3.8 Mtri/s and the fx2+ achieves 1.9 Mtri/s. The triangles are smooth shaded (Gouraud), with 1 light source.

- Page 8 Comparing the VISUALIZE fx4+ to the VISUALIZE fx4 The following features or improvements have been added to the Visualize FX+ products to significantly enhance performance, and quality, as compared with the Visualize FX4. AGP DMA Engine. This increases a driver's ability to drive the rest of the hardware to its full capacity. Immediate mode graphics (higher performance and better parallelism with applications) Display list performance for primitives with less than 6 elements (e.g., less than 6 triangles per triangle strip) Faster pixel operations (e.g., glDrawPixels)
- Page 9 Occlusion Culling - Why draw what you can't see? HP is the first to introduce hardware occlusion testing in a personal workstation, and of all the unique features in VISUALIZE graphics, this is a feature worthy of a close look. Occlusion culling requires specific application modifications to take advantage of it.
- Page 10 VISUALIZE-class graphics. Conclusion HP's VISUALIZE family of graphics accelerators for Windows NT deliver state-of-the-art features at a range of performance points. Graphics performance is affected by many variables, which makes predicting the affect on application performance inherently difficult. The actual performance will not just vary from application to application, but it can also be highly dependent on the workload used.
