Junichiro Horikawa covers the basics of forces in Houdini and how to make them using VEX.
Junichiro Horikawa is a forerunner in using Houdini for procedural works. So much so that he has an Algorithmic Design Workbook that allows you to explore multiple possibilities in the procedural modeling process. Junichiro also covers using VEX for algorithmic design and procedural modeling too, and in the latest episode, he explains forces and how you can implement them using VEX.
