Hello Oliver! Thank you for your work.
Are there any plans to improve memory efficiency in your implementation? All Gaussians3D fields are float32 now, but float16 is probably sufficient for many of them. If at least the SH coefficients became float16, it would significantly reduce memory usage because there are 48 of them. Positions, radii, opacity and rotations are also good candidates in my opinion. Of course, this can be optional, as done with depth.
