Can someone explain what is special about this? Author gave some history then started telling about new technique and only says this for explanation > Rather than having entirely distinct and clearly delineated perspectives for each player, dynamically adjust the camera(s) at a pixel level. > The most interesting part is what happens in the “no-man’s land” between, where space appears squished as the camera parameters are interpolated. What does it mean by adjusting camera at pixel level? What is happening in the wrapped area and what does that effect have to do with raytracing? Does this technique bring any performance improvements now that two camera views are being rendered.
