DirectDraw and Direct3D Support
2D Support
Software
• The hp texture color table extension.
• The hp draw array set extension, which allows rendering of multiple individual
primitives through the vertex array feature.
• HP extensions for visibility testing, which can be used directly by an OpenGL
application, or indirectly via the DirectModel or Fahrenheit APIs.
• The hp supersample extension, which provides support for full scene antialiasing.
• The vertex array, polygon offset, and subtexture features, which were only avail
able as extensions under OpenGL 1.0, are supported via both the OpenGL 1.1
interface as well as the OpenGL 1.0 extension interface for backwards compatibility.
• Support for standard Windows NT
including paletted textures and swap hint.

The hp fx and fx are identical in terms of OpenGL feature support. An OpenGL appli-
cation that runs on one device will run on the other.
In addition to their industry leading OpenGL support, the hp fx
port Microsoft's® DirectDraw and Direct3D API. Features include:
• Standard DirectDraw and Direct3D features, such as vertex and table fog, multi-
texturing, 32 and 16 bit textures, and direct framebuffer access, supported in hardware.
• 24 bit color and 16 bit Z buffers.
• Hardware support for 16 bit/pixel video overlay at all resolutions.
• Hardware support for scalable YUV video overlay.
• Hardware blits with color keying.
• Multi buffering.
• DirectX v7.0 Hardware Access Layer (HAL).

The hp fx and fx provide exceptional 2D performance for operations such as area fill,
hardware blit, hardware cursor, text display, and line rendering.
Several hardware features of the hp fx

The wide range of different graphics devices available for MS Windows® has resulted in
graphics applications having made different assumptions about how the graphics device
works. The Options tab of the display properties dialog allows the user to easily cus-

tomize the hp fx and fx
tion. Many pre-defined feature combinations are available for easy selection. These fea-
ture combinations provide maximum performance and compatibility for a large variety of
key 3D graphics applications, including PTC Pro/ENGINEER, Dassault Systems Catia,
SDRC I-DEAS Master Series, Autodesk Inventor, Alias/Wavefront Maya, Discreet 3D
Studio MAX, and SoftImage. Additionally, individual hardware performance and compati-
bility features may be enabled or disabled separately, including buffer swap synchro-
nization, fast swaps and clears, display list and lighting optimizations, stereo sync, and
the hardware accumulation buffer.
The Gamma Correction tab controls the gamma correction of 3D windows. Adjusting the
gamma value allows for correct color ramp brightness values on a wide range if different
display types.
In addition to the selection of video formats and display frequencies available from the
Settings tab, the Customize Video Formats tab allows the creation of user-defined video
formats and frequencies.
