Caustic has another video online where their CTO and co-founder James McCombe demonstrates a real-time rendering of a VGA-resolution scene at 4-5fps. The demonstration shows a 5-million triangle scene of a few cards with full ray-tracing (Primary, Secondary, and GI rays) and using procedural GLSL, trilinear filtering, and antialiasing.

Benchmarks for the HD4770 are slowly trickling in, but first to show some is expreview with some preliminary 3dmark results, compared against an HD4850.
As we can see, Radeon HD 4770 shows a 3DMark Vantage/GPU Score of P8086/6639, compared with P8367/6891 found on HD 4850, which means HD 4770 only lags behind HD 4850 by 3.47/3.79%.

I was contacted by Intersense to discuss their VCam product, based on the IS900 Intertial and Ultrasound tracking system. This podcast is an interview with their Director of Application Marketing Dean Wormell.
LG has finally priced its new LH90 series displays. Supporting 240Hz 2-Million:1 contrast ratio displays at 42,47, and 55 inches, the LED tv’s also have THX support and the ability to play DivX files over USB. The prices right now are $2445 to $4742 (depending on size), but no release date has been announced.

I’ve gotta thank Joel Martin for sending this in. He recently visited the Computer History Museum, and was amazed to find “the” teapot that has permeated computer graphics for decades.

Autodesk is hosting the “Imagine Virtual Event” May 19th, during which they’ll show demos of the new 2010 applications, have interviews with Autodesk representatives, and allow you to network with other Autodesk users.
It’s a completely virtual event, and you can register now (it’s free) on their website. Plus, you get a chance to win a 32GB iPod Touch!
Indiana University’s Data Capacitor system uses Lustre to serve massive amounts of data across the TeraGrid to users worldwide. Steve Simms, Data Capacitor project lead, and talks about it in a recent interview. The same interview also contains excerpts from Scott Micheal and Richard Durison, who use the TeraGrid and Data Capacitor to visualize results from massive gravitationsl instability simulations at the Pittsburg Supercomputing Center.
“Using the Data Capacitor s wide area filesystem I can visualize and analyze our data as it is being produced ” said Michael. “This allows me to see what is going on in the simulation as it is occurring and react quickly to any problems that might arise or make any necessary adjustments. This saves valuable CPU time and ultimately shortens our time to publication.”
Google has thrown it’s massive multi-billion dollar hat into the ring for a Web 3D Standard with a new browser plugin that allows 3D Rendering on the browser, completely via JavaScript. While Mozilla & Kronos announced an attempt to create a standard for this back at GDC09, Google has gone off on it’s own and released a separate plugin that is incompatible with the Kronos implementation. The plugin is available and open-source, so this seems to be an extend-and-embrace procedure on the part of Google, hoping that getting something out early will make their offering the de-facto standard.
The plugin is currently available for Windows and Mac, and all major browsers. It can be downlaoded from the Google O3D page

In the current issue of the BMC: Biomedical Informations and Decision Making journal, researchers at Purdue demonstrate a new algorithm for classifying and analyzing public health data based on a “Seasonal Trend Decomposition using Loess” that allows new insight into time-varying biomedical data. Such an analysis is invaluable for analysing medical emergencies such a bioterrorism or disease outbreaks.
Public health surveillance is the monitoring of data to detect and quantify unusual health events. Monitoring pre-diagnostic data, such as emergency department (ED) patient chief complaints, enables rapid detection of disease outbreaks. There are many sources of variation in such data; statistical methods need to accurately model them as a basis for timely and accurate disease outbreak methods.
A preliminary PDF is available at the link below.
