ExoTool is an HDA that use a lot of Houdini functionality. From modelisation to rendering and using the compositing operator for texturing, it can render exoplanets based on astronomical data. I personnaly use this database from NASA : https://exoplanetarchive.ipac.caltech.edu/. This work was a part of my master thesis experiment that I’d like to share with you. This article is a little demo about how this tool work and what I used to make it.
