CATS in Houdini
The Catalogue for Astrophysical Turbulence Simulations (CATS) is a collection of
magnetohydrodynamical simulations in an effort to understand
gas and stars in star forming regions in the galaxy. As part of the paper due out soon, ytini is used to demonstrate
how to render images of this data.
Here we briefly describe the Python SOP constructed for this purpose and refer the
reader to the basic Render and Image,
and Shaders tutorials for deep dives into these topics.
You can get a pre-prepared HIP file with the appropriate Python SOP - "isolatedvolume_shader_CATS.hipnc" -
included at the download files page.
To use, simply add it within a geo-node in the Network View and
navigate to PythonFITS1 to point to the appropriate file:
The code is a slightly modified version of that in the basic Python SOP
tutorial, and also uses yt to read and format the data:
