> we precompute the physical properties on the point clouds for real-time rendering. Although large in size (30 GiB for 0013_01), these precom- puted caches only reside in the main memory and are not explicitly stored on disk,

Does the cache size scale linearly with the length of the video? 0013_01 is only 150 frames. And how long does the cache take to generate?

Looks so, suspect the authors precomputed everything they can to reach the highest frame rate. Like predecoding all frames in a movie into raw pixels?

I think volumetric video should be thought of as a regular video, where the decoding and playback happen at the same time. A few papers down the line this could be easily implemented.
