Junichiro Horikawa Shows the Setup for Making Parametric Spiral Staircase With Side FX Houdini.
Junichiro Horikawa demonstrates what he calls a “rather simple setup” that will create a parametric and procedural spiral staircase. Building a staircase this way allows you to quickly manipulate and change the attributes of the model without having to remodel it.
Adding controllable attributes in Houdini requires an attribute wrangle, and Horikawa shows how to code all of that so that everything connects to the model, allowing you to alter the number of steps, radius and height attributes of the staircase.
