3D isodensity surface diagrams for one example test cube in the ISRF + star radiation configuration, comparing the SLoS-cINN prediction results to the ground truth. Here the two rows show different rotation angles of the given cube. The grey surfaces indicate a density of 10¹⁰ m⁻³, whereas red surfaces mark the 10¹¹ m⁻³ density level. The yellow star indicates the position of the B4 anaologue placed inside the cube.
