Making animations

In this tutorial, we will find out how to make animations from Hyperion output.

Example model

To start with we will use a model very similar to tutorial_images but this time we only compute the image in one wavelength bin, but for a number of different viewing angles:

scripts/flyaround_cube_setup.py

Note

If you want to run this model you will need to download the kmh_lite.hdf5 <scripts/kmh_lite.hdf5> dust file into the same directory as the script above (disclaimer: do not use this dust file outside of these tutorials!).

Making a fly-around movie

The following script describes how to generate PNG frames for an animation:

scripts/flyaround_cube_animate.py

The frames can then be combined into a GIF animation using ImageMagick:

$ convert -delay 10 -adjoin frames/*.png movie.gif

The delay value is the delay between frames in 1/100ths of a second. The result is the following:
