Houdini vs PolyWorks|Modeler

Houdini is SideFX’s procedural 3D creation system for film, television, games, motion graphics, virtual reality and synthetic-data work. Its workflow stores actions in nodes connected as networks, and supports sharing workflows and custom digital assets with colleagues. Tools cover modeling, sculpting, animation, parametric modeling, character rigging, rendering and 3D-print export. Houdini FX adds simulation tools for fluids, destruction, pyro effects, grains and cloth. KineFX supports character rigging and animation, alongside tools for hair, fur, feathers, muscles and cloth. Karma renders images in the Solaris look-development workflow, while PDG distributes tasks, handles dependencies and creates datasets for machine-learning and AI applications. Houdini runs on Windows, macOS and Linux. The free Apprentice version is for non-commercial learning and personal projects; its renders are capped at 1920x1080 and carry a watermark. SideFX lists perpetual licenses, annual upgrades, rentals, subscriptions and education licenses. Listed paid pricing starts at $299/yr, though individual options have different terms and prices.

PolyWorks|Modeler is Windows desktop software that extracts CAD entities from polygonal models of digitized parts. It creates polygonal models from point clouds in real time and repairs geometry by filling holes, smoothing surfaces, cleaning boundaries, recovering sharp edges, and making surfaces watertight. Editing includes boundary extrusion, surface offsetting, fillet reconstruction, and Boolean operations with CAD models. A NURBS workflow combines interactive curve creation with automatic surfacing to produce editable CAD-friendly models. Users can create constrained parametric 2D sketches with arcs, lines, circles, and splines, then use listed import add-ins for CATIA V5-6, NX, Creo, Inventor, and SolidWorks. Supported polygonal formats include POL, PQK, JT, Nastran NAS, OBJ, PLY, STL, and VRML 2.0; CAD formats include IGES and STEP. NURBS surfaces export to IGES, JT, and STEP, while sketches export to PWSF or IGES. Windows 10 Pro or 11 Pro 64-bit is required, with an x64 quad-core CPU, 8 GB RAM, and a professional OpenGL card with 1 GB memory. Pricing is on request; a free demo is available by request.
