monitor the memory usage

[qianqiuzzz]

Nice work! I want to know how to monitor the memory-use, I have done experiments on 3dgs and compGS, but I don't know how to compare their memory usage.

Hi, thanks for your interest in our work! We calculated CompGS memory usage by counting total number of gaussian parameters in their corresponding number of bits. Out of 59 parameters of each Gaussian, we quantize 55 parameters of color and covariance while the 3 position and 1 opacity parameters are used as is. For the quantized parameters, nearly all the memory is used to store the cluster assignment indices with less than 2% used for the codebook. (Table 6)
