Porting .ply files to Blender with colors?
by Jill P. Naiman 14 Aug '22

14 Aug '22

Hi All, I was curious if anyone has had any luck porting .ply files generated with yt into Blender with colors? It seems to port in the surfaces just fine, but they are a uniform color. From what I can gather, Blender imports .ply files with face color instead of vertex so I tried the surf.export_ply routine with "face" instead of "vertex" for sample_type, but no luck ("vertex" doesn't work either). Let me know if I can provide any more useful info. Thanks for any help, -J

Stars on volume rendering
by Elizabeth Harper-Clark 11 Dec '21

Hi all, Thanks for all your help over the last couple of days. One more question: - Can I plot particles on a volume rendered image? I have stars and I want to show where they are!

Changing coordinate system in yt
by trobolo dinni 06 Dec '20

06 Dec '20

Dear yt users, I have a common envelope simulation where two stars orbit each other. The cores of the stars are approximated by point-masses. I would like to move my coordinate system on the core of one of them with the x axis aligned with the semi-major axis of the orbit, so as to be able to analyse the data in a co-rotating coordinate system. Is there any pre-built function in yt that allows moving the coordinates system to a specific point of the box and rotate them? Or I have to do it manually? Thanks, Roberto

Axes formatting in projection plots
by Sam Patrick 06 Dec '20

06 Dec '20

Hi all, is there any option when performing a density plot with OffAxisProjectionPlot to specify whether the axes in the resulting image are labelled "x/y (pc)" or "image x/y (pc)"? I would like to output images with the latter formatting enabled. Many thanks, Sam Patrick

Shearing Periodic Conditions
by Michael Jennings 06 Dec '20

06 Dec '20

Hello All, To my understanding periodicity can be set to True for strictly pure periodic conditions. My question is if anyone has found any easy work around within yt for dealing with shearing periodic boundary conditions? I have data sets from a simulation that used the shearing box approximation and would like my yt data objects to be “aware” of shearing periodic conditions in the x direction and strictly periodic in the y direction. Has anyone find a good solution for this situation? Thanks, Michael

comoving scale annotation?
by Salome Mtchedlidze 05 Dec '20

05 Dec '20

Hello again, I am using yt slices and projections with scale annotation. I have my plots in comoving units ("Mpccm/h") but whenever I want to use the same units for annotation: slc.annotate_scale(corner='lower_right', coeff=10, units='Mpccm/h'), yt does not recognize these units. Am I missing something or only the physical scale annotation is possible ? Thanks, Salome
