ATIs TruForm in practice for the first time

Once again the old Quake 1 engine, which years ago represented a milestone in the development of 3D graphics on the PC, is attracting attention. Since the complete source code of the first-person shooter has been freely accessible to everyone for ages, programmer Matt Williams has taken on the renderer and integrated ATI's feature 'TruForm' into a game for the first time. Although the technology that makes it possible to make figures appear much more three-dimensional is officially supported 'in hardware' only with ATI's Radeon2, current cards with Radeon1 chip in the driver have the option of using TruForm 'in software'. However, as was to be expected, the performance is far behind the values ​​that will soon be possible. ATI has, however, already integrated its own extension 'GL_ATIX_pn_triangles' into the drivers in order to enable developers to program the corresponding software before the Radeon2 is released, and perhaps to make it more palatable. The following images illustrate the improvement in display quality that TruForm can bring. In view of these facts, if you want to test the upcoming feature yourself, you need the retail or shareware version of Quake1, a Radeon1 card and the patch, which can be found here . With its help, Quake1 is made completely TruForm compatible. In addition, there is a stand-alone demo that illustrates the feature using a rotating Quake2 figure. Testers willing to experiment can leave their impressions in this forum thread .
