it in the VISUALIZE fx graphics hardware. We found that the data sets many graphics workstation customers are trying to visualize are very an automobile, a tremendous performance increase can be realized by using the HP occlusion culling technology. To date, several ISVs have begun using occlusion - HP Visualize J210XC | Overview of the Visualize fx graphics - Page 4

There were some interesting problems to solve in the design of the distribution and coalescing of work up and down the geometry chip daisy chain.

The VISUALIZE fx6 texture fill rate is about twice that of the VISUALIZE fx4 texture option.

An Overview of the VISUALIZE fx Graphics
Accelerator Hardware
Three graphics accelerator products with different levels of performance are
based on varying combinations of five custom integrated circuits. In addition,
these products are the first ones from Hewlett-Packard to provide native
acceleration for the OpenGL
API.
T
he VISUALIZE fx family of graphics subsystems consists of three
products, fx
6
, fx
4
, and fx
2
, and an optional hardware texture mapping module.
These products are built around a common architecture using the same
custom integrated circuits. The primary difference between these controllers
is the number of custom chips used in each product (see
Table I)
.

product is shown in

.
This is the most complex configuration and also the one with the highest
performance in the product line. The VISUALIZE fx
4
and the VISUALIZE fx
2
products use subsets of the chips used in the fx
6
. The fx
6
and fx
4
subsystems
have support for the optional hardware-accelerated texture map module,
which contains a local texture cache for storage of texture map images. If the
texture accelerator is not present, the bus between the interface chip and the
first raster chip is directly connected.
