This article features some of the latest advances in multimedia technology.
Medical imaging solution
Nvidia launched the Quadro 2000D graphics card, designed for use in professional medical-imaging environments to help improve the accuracy and timeliness of patient diagnosis. This card is the latest addition to the company's Quadro professional graphics line, built on the NVIDIA Fermi architecture. The Quadro 2000D provides diagnostic display capabilities and application performance that hospitals, clinics, and other diagnostic-imaging environments need to interpret and manage high-resolution patient imagery.
The Quadro 2000D features two dual-link, digital-video interface (DVI) connectors and delivers gray-scale accuracy and definition of images at resolutions up to 10 megapixels. The Quadro 2000D supports 10- and 12-bit gray scale to help reveal subtle tonal abnormalities in diagnostic images, along with industry-standard Dicom monitor calibration to maintain gray-scale consistency across monitors.
An additional feature of the Quadro 2000D is Nvidia mosaic display technology, which offers users the ability to span applications across multiple, high-resolution panels or projectors. Up to eight displays can be driven from a single workstation with multiple Quadro 2000D cards installed. Nvidia SLI multi-OS technology also works in conjunction with the Quadro 2000D for driving simultaneous Windows and/or Linux environments from the same workstation.
Using Nvidia 3D Vision and 3D Vision Pro stereoscopic 3D solutions, the Quadro 2000D enables immersive 3D perspectives.
The Quadro 2000D costs $599. It is designed for HP Z800, Z600, and Z400 workstations and can connect to third-party medical displays for use in hospitals, radiology rooms, and clinics. It's also available for the Dell Precision T7500, T5500, T3500, and R5400 workstations in the US through the Dell software and peripherals program.

Screen recorder update
NetPlay Software's Instant Demo Studio 8.0 is a Windows screen recorder that creates interactive movies for presentations, demonstrations, and training. Version 8.0 introduces a new Eventline Studio Editor that is designed to help users maintain multiple presentations.
Instant Demo Studio creates interactive screencasts in Adobe Flash format and supports callout text, hotspots, voice narration, and background sound. Interactive hotspots give the viewer control over the pace of the presentation.
Instant Demo Studio 8.0 has a new feature for multiple event-line editing. Event-line editing represents each frame not as a discrete fixed unit of time, but as a unique visual event in the video. This approach is suited to editing screencasts, which typically contain periods of little or no screen activity, particularly when something is explained via narration or callout text. Hence fewer frames are required to represent the video on the event line, making it easier to navigate to the important parts of the presentation while editing.
Multiple event-line editing allows for the management of several presentations within a single workspace. This feature enables cutting, copying, and pasting between projects. Exporting to Flash or AVI can be done from any event line. The editor can also be customized for both clip size and color, providing a work environment to suit the needs of the author.
Instant Demo Studio 8.0 runs under Windows 2000/XP/Vista/7. It's available at http://www.instant-demo.com. Multiuser licenses and a free trial version are available.
Accelerated 3D Web graphics
In addition to the WebGL specification, Khronos has created a comprehensive WebGL test suite that can be downloaded for free. Implementers of WebGL-capable browsers can run the test suite and upload their passing test results to designate their implementations as conformant to the WebGL specification. More details on WebGL conformance tests can be found at http://www.khronos.org/implementers/webgl/.

Desktop motion capture
OptiTrack has released new motion capture tools called OptiTrack V120:Duo and V120:Trio.
Designed for desktop-friendly motion capture, the Duo and Trio offer multicamera, six degrees-of-freedom object tracking in a single, plug-and-play package. Each tracking system is self-contained and factory calibrated for out-of-the-box tracking.
Features include a free license of Tracking Tools motion-tracking software, compatibility with OptiTrack's Insight VCS virtual camera plug-ins, I/O options with a single cable for power and data transmission, the ability to stream or save motion-capture data, the option to do external sync I/O via the included I/O-X sync box for compatibility with shutter glasses and other hardware devices, and support for OEM integration via the Tracking Tools API.
The V120:Duo costs $1,499 and the V120:Trio costs $1,999. For more information visit http://www.optitrack.com.
