The purpose of the warping technology is to place an array of LCDs around the eye and correct for distorted image electronically rather than optically. The folks at GVU did this on a LEEP Optics HMD using texture mapping, but this adds another step in the rendering process. I guess Kaiser's hope is that this won't add too much lag. -- Chris Shaw University of Regina cdshaw@cs.URegina.ca Assistant Professor http://www.cs.uregina.ca/~cdshaw
