How to implement the figures shown in your paper and any method to visualize 4D gaussians?

Hi, as the title ask, how to generate figures of the same effect shown in your paper. Do you provide the part of code in your release version?
figure. 9

Sorry for the late reply. In this figure, I just rendered the mean and variance of each Gaussian, and manually located the pixels I wanted to display and visualizing their Gaussian function. This process is relatively simple and is not fully automated, therefore we do not contain it in this repository.
