yes I think the success of the reprojection is a much under appreciated achievement. The author repeatedly questions their claim of "seamless" but its one of the most stunning aspects that you can, for example, see your real arm outside the headset exactly map onto your virtual arm and hand inside it, as do other objects that bridge from external reality to the virtual reality view. This "seamless" nature of it is really impressive when you consider that the whole view is actually being completely reprojected and not just displayed natively from the camera feeds.
- Zee2 4y agoYeah, I really don't think people understand how critical the reprojection is. A lot of folks, apparently Karl Guttag included, think that the resolution of the passthrough is the most important factor for usefulness. And/or that the resolution of the cameras is even directly related to the quality of the passthrough to begin with! The pixel count is just one of the dozens of quality metrics, and is arguably actually one of the less important ones. I also can't tell if KGuttag believes that you can simply pass the video feed through to the user and not have an absolute usability disaster. His paragraph about the "pyrrhic victory" sort of implies that not preferring depth-correct scene reprojection was an option. In my experience, that is absolutely non-negotiable in terms of shipping a device that's usable to the majority of consumers. Another reason why folks also don't understand why passthrough is so energy intensive. You're also running an entire additional pass of steresocopic spacewarp on what is essentially four different camera feeds, on an incredibly high resolution scene reconstruction/SLAM mesh.
