Chetal Gazdar shows how you can build a spring using a procedural approach in Houdini.

Typically when you think of springs, you might also think of expressions or some VEX within Houdini. In contrast, some processes show how to create one without expressions or wrangles, but this new tutorial from Chetal Gazdar shows how you can take a more procedural approach.

Also of note, you should check out this tutorial from Will MacNeil (who is a design director at the Mill in London) that shows how to create a customizable helix setup in Houdini.
