In July 1999, the now legendary graphics card manufacturer 3dfx announced the T-Buffer, a new technology that brought cinema effects to games and thus provided significantly more realism. Pioneering improvements included soft shadows and reflections, depth of field and motion blur.

Introduced with the VSA-100 graphics processor introduced in 2000, which celebrated its premiere on the 3dfx Voodoo4 4500, the T-buffer technology made hardware-accelerated (cinema) effects such as soft shadows and reflections possible for the first time (“Soft Shadows & Reflections “), motion blur (“motion blur”) and depth of field (“depth of field blur”). The focus of the developers was on the best possible anti-aliasing (“full-scene spatial anti-aliasing”) in games.
The Napalm graphics processor that made all this possible had in detail the following specifications:
In his detailed reader article “The T-Buffer – Next Step for Cinematic Effects”, community member “andi_sco” explains the benefits of the T-Buffer technology and its effects on anti-aliasing (AA), motion blur, deep of field blur and soft shadows and reflections. The author also provides a lot of basic knowledge about 3D graphics in computer games.
Gary Tarolli, then Chief Technical Officer (CTO) at 3dfx and the mastermind behind the technology that bears his name , was quoted as follows when presenting the VSA 100 graphics processor with T-buffer technology.
The difference in render quality is dramatic when using the effects of T-Buffer technology.
Users will no longer be confronted with sharp, jagged polygon corners and the unrealistic motion effects of current 3D accelerators.
Instead, customers will now experience near-photorealistic, real-time rendered images.
