This reminds me of the 3D roller coaster simulator in Excel[1]. The difference here is this was made for readability in mind and even works without macros.
anyway, that's absolutely insane. The 3D engine seems to be laggy, on the video anyway, whereas this rollecoaster is pretty smooth !
It’s like the difference between text rendering versus decompressing JPEG images. Both can pile up enough data to exhibit lag, but you get more bang for your buck with the lighter data stream.
