Houdini is a procedural 3D and VFX software developed by SideFX, known for its fully procedural node-based architecture that allows every step of a 3D workflow to be driven by parameters, networks and expressions. In architecture, Houdini is used for procedural geometry generation, complex simulation-based form finding and fabrication data preparation where its ability to script and automate complex multi-step geometry operations provides capabilities beyond conventional parametric tools.
