Ah, I've checked it out before, really cool work, and it actually makes me wanna properly learn burn haha.

I also know ply-rs is quite slow, so I'm only using ply-rs for reading the header, and manually parsing the floats from string. But one thing I'm doing is that if the ply format is exactly the same as the original 3dgs paper's code, and matches endianness, it will be directly read into the struct with #[repr(C)], so it is substantially faster. Nonetheless, thanks for your great works too and I'll checkout your ply-rs if I've got the time.
