Alpha Buffer (Z13, Z25, and V25)
The alpha buffer holds up to 8-bits of alpha information. Alpha planes and alpha blending
logic in the Frame Buffer assist the application in rendering scenes more realistically. Special
effects that might result from alpha blending include transparency or tinting.
Multiple Video Lookup Tables
The Frame Buffer includes up to four VLTs. The VLTs provide multiple color palettes
simultaneously for color remapping and advanced color refinement.
Window-Mode Double-Buffering
Window-mode double-buffering allows multiple windows to display simultaneously from
different buffers.
Gamma Correction
10-bit gamma VLTs and 10-bit digital-to-analog converters (DACs) allow fine control of
displayed colors without color degradation.
Hardware Cursor
Hardware superimposes the cursor image over the video stream in real time, minimizing the
cursor management tasks required by the host processor.
Stereoscopic Viewing
RealiZm graphics accelerators support the display of stereo images. Stereoscopic viewing
requires a stereo-ready monitor and infrared shutter glasses with emitter module.
Multiple Video Resolutions
RealiZm graphics accelerators include programmable pixel clock generation and video timing
logic. This allows support of a wide variety of monitors with multiple video resolutions and
refresh rates. Programmable video timing also allows future monitor upgrades with only a
software driver change. Supported resolutions range from 640 x 480 up to 1152 x 864 (Z10)
or 1280 x 1024 (Z13) or 1824 x 1368 (Z25 and V25). Refer to Chapter 6 for additional
information on supported monitor resolutions.
