Creative pressures ID (Doom 3 maker) with Shadow Calculation Patent
2004-07-28 original posting on Beyond 3D, quotes id Software's John Carmack as saying:
- The patent situation well and truly sucks. We were prepared to use a two-pass algorithm that gave equivalent results at a speed hit, but we negotiated the deal with Creative so that we were able to use the zfail method without having to actually pay any cash. It was tempting to take a stand and say that our products were never going to use any advanced Creative/3dlabs products because of their position on patenting gaming software algorithms, but that would only have hurt the users.
Doom 3 maker id Software finds they have been using a technique on which Creative Labs owns a patent. Creative Labs allows their partner id Software to continue using the technique on condition that they also develop drivers for patented audio extensions (which so far were not developped by the Doom team because they are specific to Creative Labs).
John Carmack, lead programmer of id Software, is a known opponent of software patents.
