This repository contains a curated collection of 229 triangle meshes spanning a wide variety of shapes. All meshes are verified to be connected, watertight, orientable, and manifold. You can refer to a specific version of the dataset (e.g., in a publication) through the releases page.
💡 Tip: GitHub has a built-in STL viewer. Click on any model in the repository to preview it interactively in 3D.
All meshes are provided in .obj and .stl format. The collection is organized into five categories based on geometric character and topological complexity: (a) bouba genus 0, (b) bouba genus ≥ 1, (c) kiki genus 0, (d) kiki genus ≥ 1, and (e) nightmares. Here, bouba refers to smooth or organic shapes, kiki to CAD or mechanical shapes, and nightmares to very challenging shapes with unusual geometric or topological quirks. The naming system is inspired by the bouba/kiki effect.
Note that some shapes did not originally come from a triangle mesh, or came from a very poor or broken one. In those cases, we processed the shape into a connected watertight orientable manifold triangle mesh.
