We have implemented a simple visualization of the results in order
to view images of the emitted intensities. The visualization uses IDL
to read the results of the 3D RT code, performs a formal
solution for a specific and displays the result
as an image of the intensities leaving the voxel grid.
These figures are extremely helpful for discovering even
small problems with the generation and handling of the characteristics
or issues due to low resolution in solid angle or space.
Such problems will immediately show up as asymmetries in the
generated images.
We show
the results for the LTE test (with
voxels) in
Fig. 14. The limb darkening of the test sphere
is clearly visible in the figures. The slight pixellation and asymmetries
are due to spatial and angular resolution. Note that the scales of the different
panels are different due to the changing orientation of the data
cube. The generated images for the
test case
with
and
voxels are shown in Figs. 15
and 16, respectively. For both figures, the
source functions were calculated with
angles. The images show
much less pixellation and far less artifacts than the images shown
in Fig. 14. The results for the
test
case are shown in Fig. 17, they look similar to
the
case with the same grid sizes.
