I want to know how to visualize Gaussians like your Fig.1

[Min-Hyuk98]

Thanks a lot for your great work. I want to visualize the gaussian model as you did in the fig 1. Thanks

This visualization is made by manually controlling the gaussian scales and opacity.

I first shrink the scale and enhance the opacity to draw the solid gaussian centers with customized colors (the solid points). Then I just enlarge the gaussian radius and decrease the opacity to draw some ring effect around the centers (the blurry one). Hope this will be helpful.
