How is query speed measured? #38

Hi, really nice work!

I wanted to ask you, how did you compute the query speed of tables 3 and 4 of the paper?

I've observed that the current implementation stores each level of language features on a different set of gaussians. Therefore you require 3 rasterization steps to obtain the 2D language features for a given point of view. Are you taking this rasterization and the posterior decoding time into account, or you are just measuring the query matching with the CLIP features?

Thank you!
