RealityEngine: Video/Film

[Click to download larger version]

RealityEngine graphics supercomputers have been designed to provide users in digital video and film production with a multi-purpose computer platform that can meet, and exceed, the needs of CGI, broadcast graphics, image processing and video post-production.

RealityEngine has key advantages over any other computer system for use in production environments. In addition to the renowned ability of the IRIS line for 3D animation, RealityEngine brings fast hardware rendering, interactive effects and image processing to film and video professionals as well as scientific and technical users who require the ultimate in high-resolution imaging.


Video input and output

RealityEngine graphics supercomputers offer a wide range of video input and output devices. The RealityEngine systems come standard with a number of different video resolutions. Any 640 x 486 or 768 x 576 area of the high resolution computer display can be output as independent high quality NTSC or PAL composite video. Both the IRIS Crimson and IRIS POWER Series systems offer multiple VME slots for adding single-frame animation controllers or broadcast quality live-video processing devices. Multiple analog and digital video formats are supported.

Display capability

Through the use of programmable video output formats, RealityEngine is capable of a wide range of display options. SMPTE 240M HDTV, 1250/50 HDTV, 1600 x 1200 non-interlaced, 1280 x 1024 workstation standard, NTSC, PAL and VGA are just a few of the many formats included as standard with the system. With the use of one of the Silicon Graphics video options, such as the VideoSplitter/2, RealityEngine is capable of multiple high and low-resolution outputs on a single system.

Software Support

Among the over 1400 software packages available for IRIS systems are applications for animation, rendering, digital paint, editing, compositing, titling and image processing. The RealityEngine can run software like Video Composer from Wavefront, Power Animator from Alias, nTitle from XAOS Tools, Integrated Research's Integrated Video and hundreds of other applications.

Software developers can take advantage of the ImageVision Library. ImageVision Library is an object-oriented extensible toolkit for creating, processing and displaying images. RealityEngine's special hardware acceleration for ImageVision Library operations makes it the optimum platform for image processing yet it retains full compatibility with other Silicon Graphics systems.


RealityEngine systems, like all Silicon Graphics computers, can be configured in a number of different ways; from the IRIS 4D/310 RealityEngine and IRIS Crimson/RealityEngine single-CPU systems to the 8-CPU IRIS 4D/480 RealityEngine, which combines supercomputer compute performance with the world's fastest computer graphics.

Any IRIS Crimson, POWER Series or SkyWriter system can be upgraded to RealityEngine performance with a simple board-swap. IRIS SkyWriter systems include two full RealityEngine pipelines for twice the number of outputs from a single rack-mount enclosure.
