Web1 day ago · I'd like to get an interactive visualization of a faitly massive 3D point cloud in a tkinter python application I've been working on. I already have some matplotlib plots implemented so the first step was to use a 3D scatter plot for 3D visualization. Although that basically works, it is really really slow for a useful number of points.
