Yesterday ↑Engine John himself appeared at Apple’s WWDC07 and for the first time presented his next generation wizardry ↑id Tech 5. Carmack showed off a short technology demonstration—allegedely handling some20GB of textures—, but didn’t say much beyond the ↑official press release:
The ground breaking technology unveiled today will power id’s new internally developed game and will be available for licensing to third parties. The new id rendering technology practically eliminates the texture memory constraints typically placed on artists and designers and allows for the unique customization of the entire game world at the pixel level, delivering virtually unlimited visual fidelity. Combined with a powerful new suite of tools designed to specifically facilitate and accelerate this content creation process, id Tech 5™ will power games that contain vast outdoor landscapes that are completely unique to the horizon, yet have indoor environments with unprecedented artistic detail.
You can watch the complete ↑WWDC 2007 keynote address[Carmack appears at around 12min], or watch Carmack only, filmed from another angle, ↑at YouTube. Things to remember are, that there is a new id game in the making, and that game modding sooner or later will have a new Carmackian engine to prey on.
