This 4D tech feels like a Time Machine. I call it the Geospatial Memory Palace.

Same place, different time. Walking through summer and winter simultaneously. Imagine seeing your memories when and where they happened, instead of scrolling through a camera roll. The spatial memory palace continues to come to life. I predict this technology will be foundational, not just for augmented and virtual reality, but also for robotics. Check out my long form YouTube video where I go deeper into colmap SfM, multiset VPS, monocular depth, pose graph optimization and all the techniques used to make this stuff a reality. but don’t worry, we also get super philosophical about what adding X, Y, Z plus time to the mix really means.
