Chapter 5 PowerShade: Enhanced 3D Rendering in Software
PowerShade is software that allows lighting, shading, and hidden-surface removal. It offers the
capability for both surface rendering and volumetric rendering. (Volumetric rendering is available on
supported devices only.)
PowerShade is not supported on the GRX or on any grayscale version of the Models 705, 710, 715 or
725. (See your Owner's Guide for more details on hp 9000 workstations.)
Because PowerShade functionality is API-independent, it is fully supported by Starbase, hp-PHIGS, and
hp PEX. For more information, refer to the appropriate API manual set.

Compatibility Considerations

You should consider the following information before you run an hp-UX 9.x application on an hp-UX
10.x system. This applies to applications that use hp PEXlib, Starbase, or hp-PHIGS graphics libraries.
• If your hp-UX 9.x application uses PowerShade functionality, you need to make sure you have
PowerShade installed on your hp-UX 10.x system for it to run. To do this, use swlist to confirm
that the PowerShade fileset has been installed on your system.
• If your hp-UX 9.x application uses hp VMX and it is designed to send output to an X terminal,
you need to have PowerShade installed on your hp-UX 10.x system.
____________________________________________________________________________________
Note: Even though some graphics devices automatically have PowerShade capabilities, you still need to
have PowerShade installed in order to output graphics to a remote X terminal.
____________________________________________________________________________________
As part of the transition to only supporting 3D computer graphics within the X Windows environment,
the Release 10.x versions of Starbase no longer support input directly from interactive devices such as a
keyboard, mouse, trackball, digitizing tablet, button box, knob box, or similar devices. Applications
should request input of this type through the X server.
The result of directly accessing an interactive input device from Starbase in Release 10.x is undefined. If
your application reads input directly from a mouse, keyboard, etc., using Starbase input calls, you should
modify that application to use Xlib calls to read data from these devices. (This statement does not apply
to hp-PEXlib since that API does not include input mechanisms. The PEXlib programmer should
already be using Xlib for input.)
Starbase applications that are linked with hp-UX 9.x shared or archived libraries may see different input
handling behavior when run on an hp-UX 10.x system.
Versions of hp-UX prior to Release 10.x will continue to support direct input as before. Hewlett-Packard
documentation will continue to describe input calls for Starbase because these manuals are also used
with versions of these APIs that support direct input.
