I am trying to see if I can create a mesh-like grid in desmos, similar to the 2D grid, but in 3D. Any ideas?
Something like this?

Just to note, a newer calculator feature is the acceptance of variables for graph bounds in the wrench menu:
So you could have t ranges set to graph bounds as well.

Define “volumetric”?
related to volume … in this case a grid with volume, that is a 3D grid.
The adjective “volumetric” is very often used in rendering:
volumetric rendering is a computer graphics technique used to visualize 3D objects by simulating how light interacts with fog, smoke or clouds. Traditional rendering only models the external surfaces of objects using polygons. Volumetric rendering also models air, glass, water and other materials with voxels (volume pixels) and this allows to create more realistic renderings.

Is there a way to get the grid from a list of 3D points?
cool! So essentially it’s just a higher resolution rendering for liquids and gases.
yes, but it depends on what the list of points represents …
the list of points may for example represent a list of triangles …

I’m trying to get something similar to how gravity deforms spacetime. Could I apply some sort of function vector field to it?
If you look for Desmo 3D vector fields you can find many examples …
here’s one such example:

I’m trying to see if I can apply a function that can be smoothly applied to the gird lines themselves to show how different masses are bending spacetime. So basically taking each vector component’s function and applying it to the grid, although I don’t know how to do that.
I that case the grid should be drawn with vectors and not with straight lines.
Then you can apply a function to each vector and draw the resulting vector.
If I have time I’ll try to give you the idea.

Im trying to get something like GR Space transformation | Desmos but in 3D and with custom functions for each component
ok, I get it now …
here’s the same graph in 3D:

Is there a way to apply custom functions to the grid?
You can also combine those three functions into a single one:

Thank you so much! It works now
I simplified the code a lot and added some nice options:
