Rendering a Pore Network with color bar

Hi, Marco.

Thank you for vedo, it is a really nice and convenient lib.

I have been trying to render Pore Networks with vedo inside jupyter notebooks. I have successfully plotted Pore Networks without color bars, but unfortunately I’m struggling to add color bars (to colorize according to pressure or solute concentration for Fluid Flow in the PN).

I feel like I’m missing something very basic here. Would you mind to give me some advice please? I’m providing a MWE below (next comment).

Cheers, Diego

Thanks, Marco!

I think we can close this issue since you have worked on it. I will test it in another dev environment I have, and if I find any problem, we can re-open the issue.

Cheers!

…oh I see a few weird things there…

1. being a physicist I'm immediately suspicious of the `pore_concentration` and `throat_concentration` spanning so many orders of magnitude... does that really make sense?

Thank you for your observation! Indeed, this example does not make sense, it is just a toy problem to check if I can generate the visualization in notebooks. Maybe I can provide a more realistic example to add to vedo’s gallery (I have to check it, because it is generated by a proprietary software).

2. you cannot assign a single `float` as a color input of Sphere and Cylinder, because `vedo` will try to map this onto the default jet scale in range [0,1]. You should explicitly map the scalar to a [r,g,b] color using `colorMap()`

Hmm… so this is the proper incantation, I see! Thanks!!

maybe this is better?

A lot better!
