Maya 5 First to Deliver Advanced Rendering Power

by Leveraging the new mental ray 3.2 Technology

Alias/Wavefront(TM), an SGI (NYSE:SGI) company, revealed today that its Maya(R) 5 software is the first 3D package to leverage advanced rendering innovations from mental images' new mental ray(R) 3.2 rendering technology. Alias/Wavefront and mental images(R) continue to forge ahead with mental ray for Maya(TM) development, after each company recently accepted awards from the Academy of Motion Picture Arts and Sciences for their advanced technology solutions.

"It's exciting to see two of the world's most advanced graphics companies working together to provide customers with even greater control over content," said Samantha Staples, Principal & Senior Analyst at Acacia Research Group. "Mental ray is quickly establishing itself as the 3D industry's renderer of choice - this coupled with Maya continuously being a leader in the entertainment market means a powerhouse of technological imaging capability will be available in the newest version of Maya."

Advanced Rendering Enhancements Added to Maya

Mental ray for Maya 5, which is now distributed and installed automatically with Maya software, offers physically accurate, photo-realistic rendering options such as global illumination, caustics and ultra accurate lighting calculations. Highly requested features such as support for particles and hierarchical subdivision surfaces, as well as light mapping optimizations, are now available in Maya 5. With the new mental ray 3.2 core architecture, more efficient use of memory and low-level CPU optimizations offer significant performance improvements to rendering pipelines.

"The integration of mental ray with Maya produces better looking renderings, but more importantly for us, it increases our productivity," commented Tristan Salome, CTO at nozon.com.

"Maya's diverse customer base pushes rendering technology further and further as new productions seek higher quality and more realistic imagery," said mental images President and Director R&D, Rolf Herken. "The integration of mental ray 3.2 into Maya will provide users with the most powerful rendering option available today. It fits perfectly with mental images' agenda to make mental ray the uniquely sophisticated and most pervasive renderer used in the industry."

Both Alias(R) and mental images were honored on March 1, 2003 by the Academy of Motion Picture Arts and Sciences. Mental images received a Technical Achievement Award for mental ray, "a highly programmable computer-graphics renderer incorporating ray tracing and global illumination to realistically simulate the behavior of light in computer-generated imagery." Alias/Wavefront received the highest honor the Academy can bestow - an Oscar(R) statuette for "...the development of a 3D animation, dynamics, modeling and rendering production tool known as Maya. With its significant and dominant impact on the motion picture industry, the Maya software package offers a robust and widely used commercial visual effects tool with a rich infrastructure for extension and customization."

"Industry recognition proves what our customers already know," commented Shai Hinitz, Maya Product Manager. "The combination of Maya and mental ray is opening a new world of unprecedented image creation possibilities for Maya's extensive community."

Alias/Wavefront Customers Get First Access to mental ray 3.2

Alias/Wavefront customers will be the first to have access to mental images' new 3.2 standalone renderer. Mental ray 3.2 standalone is available for the Windows(R), IRIX(R) and Linux(R) operating systems and now for the first time, Maya customers working on the

Mac(R) OS X platform can also take advantage of the mental ray standalone renderer. Mental ray for Maya is a standard feature of Maya 5 which will begin shipping in May 2003. The mental ray 3.2 standalone renderer will be available separately in early May 2003 from Alias/Wavefront. For more information please visit www.aliaswavefront.com.
