“Without compromising the overall performance of current PC technologies or compatibility with existing 3D games, TruForm breaks through these challenges to deliver the smoothest and most natural images ever seen on a PC.”īy employing N-Patches (also known as PN Triangles) – a new type of higher order surface composed of curved rather than flat triangles that was developed by ATI and is supported in Microsoft’s DirectX™ 8.0 and OpenGL™ technologies - TruForm permits surfaces to be generated entirely within the graphics processor, without requiring significant changes to existing 3D artwork that is composed of flat triangles. “They still tend to look like a collection of geometric blocks with textures painted on them, largely because of limited bus and memory bandwidth.
“Despite recent improvements in the graphical quality of computer games, for example, most 3D objects – especially characters – still do not appear very lifelike,” said Toshi Okumura, Senior Product Manager, Desktop Marketing, ATI Technologies Inc. (TSE: ATY, NASDAQ: ATYT), a world leader in graphics, video and multimedia solutions, today unveiled TruForm™, a new rendering technology developed for future generations of graphics processors that will help to deliver the smoothest, most natural 3D images ever seen on both existing and next-generation 3D games and personal computers. More importantly, should anyone considering upgrading to a 5850 or a 5870 be concerned about the tesselation performance of either card? Is Fermi that much better and does it matter? I have no doubt that Southern Islands will improve tesselation capacity however, whether that is simply to take the title away from Nvidia or whether we, as consumers, will see a tangible improvement in the near future remains to be seen. However, will this translate into an increased number of games that make use of this capacity? Can we expect to see more and more titles that are optimised to take advantage of one of Fermi's strongest selling points? Will such optimisation take place on a level playing field, or can we expect to see something along the lines of the disabled in-game AA for Ati cards present in the Arkham Asylum title? To take Metro 2033 as an example, a TWIMTBP game, the increased tesselation capacity of the 480 isn't really showing much in game advantage. This can in part be attributed to Fermi's superior tesselation performance: Nvidia, if and when they finally get sufficient stocks of 480's and 470's on to shop shelves, will undoubtedly put a lot of effort into spinning an area where they have a clear advantage. I expect that we'll be hearing more and more about tesselation over coming months. Tesselation, it seems to be everybody's favourite new word, but what implications does it have?
