I tried looking up a technical publication on this technique but the journal article is straight trash [0]. That said, I found a useful post where folks were trying to explore this style of rendering [1]. It’s interesting to see that in the demo videos the cameras move in a straight path. Apparently there is some wonkiness that comes from changing the view orientation.
From [1], I’ll leave by cross posting some useful links: experimental rendering techniques with Quake [2], Minecraft [3], and a cool article about visualizing projections [4].
