How to create a 3D model in nodes?

To create a 3D model in nodes, use a procedural workflow—connect node-based tools (e.g., Blender’s Geometry Nodes, Houdini) to build and modify geometry step-by-step instead of manual modeling. Nodes are reusable blocks for tasks like adding primitives (cubes, spheres) or deforming shapes. Linking them lets you adjust the model dynamically—changing a node’s value updates the whole design instantly. For beginners, start with simple setups (e.g., combining two shapes with a boolean node) in Blender. Its pre-built nodes teach the basics without needing to code.
