Intel Develops Technology For Interactive, Realistic 3-D Graphics

Technology to Deliver More Realistic 3-D Games; Better 3-D Scanners

LOS ANGELES, Aug. 14, 2001 - Intel Corporation today announced that it has developed a new software technology called Light Field Mapping (LFM) that helps to create more life-like 3-D images for interactive applications, such as games, by correctly modeling light reflection properties of 3-D objects. This technology will allow game developers and animators to use more realistic objects and scenes in their 3-D creations.

Developed by Intel Labs researchers, Light Field Mapping technology is a compact, efficient and highly accurate method for representing light reflectance properties of real and synthetic objects. LFM has the potential of making photo-realistic computer graphics possible on the PC and could become a new standard in computer graphics, improving texture mapping, a 3-D graphics technique commonly used today. Intel Labs researchers will present technical details of this technology at the SIGGRAPH trade show here today.

"The big challenge for the 3-D graphics industry today is how to bring the realism we know we are capable of delivering into interactive 3-D graphics," said Radek Grzeszczuk, senior research scientist with Intel's Microprocessor Research Labs. " The combination of a fast and simple rendering routine, small data sets and ease of content creation features in LFM will help bring more realism to computer graphics without sacrificing interactivity."

Applications of Light Field Mapping Technology
Three-dimensional graphics can be used to produce synthetic images that often cannot be distinguished from reality - such as those in movie special effects. However, producing graphics with this level of realism takes a long time to compute, making it difficult to deliver top quality in interactive uses, such as video games. LFM will help bring high quality 3-D to real-time, interactive applications.

LFM also has a great potential for improving the 3-D scanning industry because it can correctly reproduce the appearance of physical objects, even those with very complex surface reflectance properties. Intel Labs researchers are working on developing a complete solution for acquisition, delivery and visualization of 3-D models that are highly realistic and acquired completely automatically, with minimal human intervention. Intel's LFM technology should help create photorealistic 3-D content quickly and easily.

Technology Availability
Over the next few months, Intel will be talking to game developers about the use of Light Field Mapping technology in future 3-D game engines. Intel will also be talking to 3D scanner developers in the same timeframe. Intel expects to see initial diffusion of LFM in about 18 months, with broader diffusion in about two years.
