how can I use meshoid to create 3-d plots of conserved quantities category:Q&A

[jainary4]

I am working with molecular cloud data , using the surface density method in meshoid i was able to create 2-d images of clouds , my supervisor said me that using the same code and the PPV and PPP functions I can create 3-d rendering as well , i am not sure how to use that. Can someone please help me with that. Thank you.

Welcome!

Meshoid's methods for depositiom of 3D unstructured data to a 3D Cartesian grid are: Meshoid.DepositToGrid and Meshoid.InterpToGrid.

For an example of these in use, see e.g. this script where I put unstructured GIZMO HDF5 data on 3D cartesian grids so that I can do a FFT and get power spectra.

Re: visualization: Meshoid does not have any methods explicitly for rendering 3D Cartesian grid data. It only implements the interpolation/deposition, then you have to plug it into some other backend to get a visualization. This is analogous how you have to plug 2D projected maps into e.g. matplotlib to get a plot.
