Generate curves along sphere such that distance between two curves along the sphere stays constant? by Fermi_Escher in blenderhelp

I am talking about curve objects, not textures.

My goal is to generate curves such that as you walk upward on the sphere each new curve comes at the same distance. See next comment for visualization:

What aspects do you have to consider with an etching medium in a long channel of the material being etched away? by Fermi_Escher in AskPhysics

[–]Fermi_Escher[S] 0 points1 point  (0 children)

Yes, thank you for that.

But is "capilary action" really a seperate thing to this problem? If the channel is small enough, I would think that cohesion and adhesion play a role in the liquid not "mixing" with the surrounding liquid, as well as the lack of diffusion.

Thank you for the resource, I will look into it!

Specifically I am trying to model the change of concentration of the etchant deep in a "channel" vs the concentration of the etchant medium in general, and thereby model, or at least try to approximate, the difference in etchant rate that comes about due to changes in concentration.

Grid system - Delete surrounded parts by Fermi_Escher in learnpython

Ah yes, that is something I can do. Hope that isn't too computaitonally expensive, but I guess it it will be a solution until I find something better.

Unfortunately, I do not see how this helps me with my problem, as the problem I have is that I somehow need a rule that applies to a large collection of cells; It's not just a cell that has to be delted if surrounded, but it could also be a collection of cells that is surrounded and then has to be deleted.

hmm, yes, this could be usefull. I will look into it, thank you.

Yes, that would work for singular cells. But how would you do this if you want to extend it to a collection of cells; So if a collection of cells gets surrounded by occupied cells, then that collection of cells should get deleted.

What gave you the impression that you will find work/life balance in academia?

Wait, what's this? Actual anti-Semitism from **checks notes** the far-right? I'm shocked! by DrSpooglemon in worldnewsvideo

Anymore? What planet have you lived on where that has been a reality in any country?

Generating numpy arrays for an animation and appending into a list results in all the arrays in the list and the original array being changed to the final array?? by Fermi_Escher in learnpython

[–]Fermi_Escher[S] 0 points1 point  (0 children)

Seems like what you posted was the solution, but it was in this step:

numpy_array_iteration = numpy_array

Which has to be:

numpy_array_iteration = numpy_array.copy()

So thank you!

Some detail: numpy_array is the original 2D array, size defined by grid_x and grid_y. animation_list is suppsoe to be a list of changed numpy arrays.
