mental images® Unveils iray Rendering Solution



SANTA CLARA, Calif. and BERLIN, Germany — Sept. 30, 2009— mental images®, an NVIDIA company, today
introduced iray® – the first fully GPU accelerated, commercially supported, turn-key rendering
solution for a wide range of 3D graphics application developers. iray technology leverages NVIDIA®
graphics processing units (GPUs) to deliver unbelievably fast photorealism to designers, engineers
and consumers.


Life-like graphics can now become interactive as iray rendering technology exploits the massively
parallel processing power of the GPU, enabling more convincing 3D visuals, greater levels of
creativity and faster decision making. “With iray rendering technology, what used to take product
designers, visual effects artists and CAD users hours to render can now happen in a matter of
minutes without compromising the quality and detail of the image, said Dr. Jon Peddie, president,
Jon Peddie Research. “The advent of iray is changing the face of this industry by increasing the
standards in rendering efficiency as we know it.”


iray technology speeds the creative process by easily enabling designers to accurately simulate
their creations using materials and lighting that relate directly to the physical world experienced
every day. Because it’s highly scalable, interactive and physically accurate, iray technology allows
design and engineering professionals to produce the highest quality final-frame output without the
complexity inherent in other solutions.


With tight integration with mental ray® technology – mental images’ renderer, which is extensively
used in feature film work and within the leading design and creation tools from Autodesk, Dassault
Systèmes
and Parametric Technology – iray rendering technology will empower millions of users with
the ability to change the way they create synthetic images.


“The combination of iray and NVIDIA GPUs is an astounding achievement, demonstrating our undisputed
leadership in computational graphics,” said Dan Vivoli, senior vice president, NVIDIA Professional
Solutions Group. “The ease-of-use and remarkable speed of iray brings interactive photorealism
easily within the reach of any creator or consumer of 3D content.”


iray rendering technology significantly improves how designers, engineers and other content
development professionals work with rendering tools to produce high-quality, photorealistic imagery.
Harnessing the power of the GPU and the NVIDIA CUDA™ parallel processing architecture, iray
technology progressively refines an image until maximum detail is reached, providing a single
process that smoothly combines interactive pre-visualization and final frame rendering. iray
technology requires only a small number of intuitive settings relating to the physical world that
delivers a “push-button” rendering experience for creating final-frame photo-real images.


“It’s no secret that users want to utilize the power of GPUs for photorealistic rendering,” said
Rolf Herken, CEO and CTO, mental images. “With iray, we deliver a solution that not only leverages
the GPU in the most efficient manner but also raises the bar for what is defined as photorealism in
rendering.”

Mieux comprendre le FBX

Pour revoir ses bases et accroître ses connaissances sur le format d'Autodesk FBX permettant un échange d'éléments 3D complets entre différents systèmes et logiciels, je vous invite à consulter, en anglais le white paper à la fin de ce post.

Extraits :

"One of the most widely used 3D interchange formats on the market, Autodesk® FBX® technology is designed to enable workflows built around multiple 2D and 3D digital content creation applications. Such workflows are the lifeblood of large production houses and small boutique studios. In this white paper, you learn how FBX technology can help improve workflow efficiency and productivity and how to use it to enable interoperability among Autodesk® 3ds Max®, Autodesk® Maya®, Autodesk® MotionBuilder ™ software, and other applications."

"FBX is much more than a file format. The FBX technology family of tools—SDK, plug-ins, and viewer, as well as the FBX file format—offers a comprehensive data interchange solution. In the same way that PDF files let you share documents with users who do not own the word processor or page layout program those documents were created with, FBX technology lets you exchange data between 2D and 3D applications. The FBX file format, however, is more flexible than the PDF format, because data passed between applications via the FBX file format retains its ability to be manipulated."

"The FBX technology family of tools provides universal 3D asset interchange, helping to break through data compatibility
barriers. FBX is a platform-independent file format that enables you to access legacy content after upgrading your pipeline to take advantage of the latest 3D tools; exchange digital assets with other studios whose pipelines are standardized on tools different from your own; and use multiple 3D tools to realize your creative vision in the most efficient manner possible."
