BACKGROUND 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+. The HP VISUALIZE fx+ family of products take full advantage of the latest technology to accelerate applications that use the OpenGL graphics API, achieving outstanding performance with an industry-leading feature set. It is a secondgeneration product family, designed specifically to take advantage of the latest in processor and system design technology. The following sections focus is on the capabilities of the graphics, describing the unique features, strengths and technical information on the performance differences between the ultimate performance of the VISUALIZE-fx6+ and the lower cost VISUALIZE-fx4+ and VISUALIZE-fx2+, and how the differences can be expected to affect application performance. VISUALIZE-fx+ Graphics - Features Let's refer to the family ranging from the VISUALIZE-fx6+ to the VISUALIZE-fx2+ as the fx+ series family, and abbreviate its members as fx6+, fx4+, and fx2+. For compatibility and ease of application certification, the same features are supported across the product line. Key 3D Features: AGP2X (133MHz) support, where AGP is the Advanced Graphics Port AGP DMA (Direct Memory Access) support OpenGL 1.1 compliance - Hardware acceleration of Key OpenGL extensions - Most OpenGL 1.2 features are supported as extensions 18MB SGRAM frame buffer memory: - 24-bit true color, double buffered - 24-bit Z-Buffer - 8-bit overlay planes - 4-bit stencil and 5-bit Windows ID Optional Texture acceleration and dedicated texture memory Full set of OpenGL features accelerated in hardware: Hardware Accumulation Buffer (Requires driver version 1.12 or later) for advanced features: - full-scene anti-aliasing - motion blur - multi-pass rendering algorithms Anti-aliasing for vectors and points Gouraud shading (smooth shading) Alpha blending for transparency Fog/depth cueing Optional hardware texture acceleration: Dedicated texture acceleration processors Dedicated texture SDRAM memory Point-sampled, bilinear, and trilinear MIP mapping 3D texture mapping Shadow texture mapping HP Color Recovery technology for double buffering at 1600x1200 resolution Hardware acceleration of occlusion culling Stereo vision support, with refresh rates up to 120 Hz (effectively, 60Hz each for the left and right eye) Although the fx+ series was primarily designed for OpenGL features and performance, 2d performance and features are important in the design. Gone are the days when to get 3D graphics performance, you needed to compromise the graphics performance for word processors, spreadsheets, etc. The fx+ series also has hardware support for Microsoft's DirectDraw interface, which is useful for accelerating viewing video clips for computer based training or as part of web browsing. 03/12/99 HP 1
