Than you! A Small addition: My matplotlib version needs ax = fig.add_subplot(projection='3d') instead of ax = plt.gca(projection='3d')

This is a nice tutorial. Sir, we need another tutorial on Neutrons interaction with materials and damage estimation in Geant4. we are missing your geant4 tutorials. Thanks

Thanks for the videos. I have a question about multivariate data. I have three independent variables and would like to see their occurrences by coloring the data based on their probability densities (plot type can be contour, surf etc.) Which function should I use? Could you please help me with this?

Nice

This is great for hypersurface functions with only two variables e.g. f(x,y) = x**2 + y**2 - 1. Would be really great however to do a tutorial for hypersurfaces acting on all 3 axes e.g. Plot the function f(x,y,z) = z**3 + y**2 - x*4 + 1

I am curious that how would it visualized. Would it not be a density function spanning the entire 3D volume? It would then look like a cloud with regions having higher density(darker colour shade) for higher values of f(x,y,z) than others. Or, maybe you can have a collection of points spaced uniformly in x,y,z with each of them being coloured based on the values of f(x,y,z).

@hartnady 10 месяцев назад

Pretty much yes - you are effectively drawing a 4 dimensional object on a 2D surface, so would need something like pixel weights (clouds as you suggest) or a colour code scheme to represent the extra dimension@@bridge5189

@@bridge5189 I think the problem is better suited to Virtual Reality devices that render images in 3D (ironically though, still through a 2D medium albeit stereoscopic). The fourth dimension could potentially be represented with sound using a VR headset? Probably overthinking this now...
