PERFORMANCE

Feature: Master controller engine on the Sun XVR-4000 graphics accelerator that links to four rendering units:

• MAJC-5200 processor chip (geometry and lighting calculations) FBC3 ASIC rasterizer
• 32 MB RDRAM (program storage and cache of display lists)
• 256 MB SDRAM (texture storage)

Function: The master controller engine is the interface to the Sun Fireplane interconnect on the server. It provides a single OpenGL interface to applications that allows system processors to concentrate on running applications.

Benefit: Leverages parallelism to deliver increased performance without programming complexity.

Feature: Dedicated memory on the Sun XVR-4000 graphics accelerator:

• 144 MB of frame buffer memory
• 1 GB (4 x 256 MB) of texture memory

Function: Large frame buffer memory provides support for higher resolutions with more samples/pixel. Large on-board texture memory enables interactive visualization of larger volume data (3-D textures)—-reducing system memory access.

Benefit: Provides users with more insight into data and increases system efficiency.

Feature: Dedicated on-board convolve filter chips.

Function: The convolve chips apply a 5 pixel x 5 pixel programmable, radial filter to the samples (maximum of 16 per pixel) rendered by the rasterizer and compute a weighted average of the samples to generate each pixel value. The samples are randomly located in a 64 x 64 sample grid per pixel.

Benefit: Provides very high visual quality and realism for large screen displays.

FLEXIBILITY

Feature: 3-D stereo resolution support.

Function: Provides users using stereo glasses with 3-D depth perception and allows users to have a more interactive experience with data.

Benefit: Increases productivity by providing more insight into data.

Feature: Dynamic video resizing of the rendered image in display memory to the display output via S-video.

Function: Delivers guaranteed frame rates and allows the entire display screen to be dynamically resized to NTSC/PAL format for recording to a video recording device via the S-video output.

Benefit: Provides predictable performance and increases productivity.

Feature: Framelock for synchronizing multiple displays and genlock for synchronizing to an external video source or synchronizing multiple frame buffers.

Function: Allows a multidisplay environment with edge-blended, seamless, stereo displays. Genlock, used in conjunction with framelock, provides more precise synchronization and enables real-time image warps for curved screen and dome displays.

Benefit: Enables increased display resolution, providing more visual clarity.

Feature: S-video support.

Function: Provides analog S-video output in NTSC or PAL standards for display on a TV monitor or for recording to a VCR.

Benefit: Enables collaboration among team members.

Feature: Adjustable gamma correction table for each video stream.

Function: Provides a truer color representation with an extra level of color correction.

Benefit: Increases data comprehension and usability.

Feature: Multiple hardware color maps in each video stream.

Function: Allows multiple windows with different color map requirements to be opened without color flashing.

Benefit: Provides greater flexibility and a better user experience.
