Keenan's 3D Model Repository

Below are some models I've put together over the course of my research. In contrast to scanned data, which often provides only the surface geometry, the idea here is to provide a few models that include all that other stuff like textures, control cages, etc. Note, however, that many of these models are not ideal for testing the robustness of some algorithms since most of them are noise-free and perfectly manifold—compare with the models available from the Stanford 3D Scanning Repository and the AIM@Shape Project.

Wherever possible I have released data into the public domain, which means you can do whatever you like with it without asking for permission or acknowledging the source (although acknowledgement is certainly appreciated!). I specifically request that the editors of ACM Transactions on Graphics do not require authors to include copyright information for this material in figure captions or videos.

Jerry the Ogre
preview

Several people have asked me for the model of this ogre, who starred in our ray tracing paper. Since there are few models available to researchers which include anything beyond a triangle mesh, I've also included the following data:

  • the original Catmull-Clark control mesh
  • five blend shape triangle meshes (with normals)
  • occlusion maps for each of the blend shapes
  • a texture atlas
  • a diffuse color map
  • a displacement map
  • a normal map
  • a geometry image

San Diego Convention Center
preview

Building inspired by the San Diego convention center (originally designed by Arthur Erickson). The archive contains:

  • a mesh of the building
  • a mesh of a ground plane
  • shadow maps for a directional light source
  • texture maps for baked indirect and environment-based lighting

Yeah Right
preview

As in, yeah, right, we can come up with a good texture atlas for this... The model has the following notable properties:

  • both the surface and its embedding are manifold
  • it has genus 131
  • the archive includes pure quad tessellations of the surface

Chiba City Blues

An abstract city. The archive contains:

  • a polygonal mesh of the city
  • a triangulated mesh of the city
  • a mesh of a ground plane

Oloid
preview

The developable oloid surface at various resolutions, as both a quad and triangle mesh. Also includes code to generate the oloid at any target resolution.

Mechanically, the entire surface of the oloid comes in contact with the ground as it rolls along a linear trajectory. Here's a rigid body simulation of the model, courtesy Breannan Smith: Movie (QuickTime, 588KB)

Pittsburgh Bridge
preview

A scan acquired in the City of Bridges, at CMU's Panoptic Studio. The archive includes data from several stages of the reconstruction process, starting with the raw point cloud all the way to a closed, remeshed surface with nice triangles. The final surface has genus 3, since it includes part of the ground. Many thanks to Tomas Simon, Tim Godisart, and Stelian Coros.

The archive contains:

  • the original point cloud (including colors)
  • a processed point cloud
  • the original reconstructed mesh
  • an isotropic remesh (with boundary)
  • an isotropic remesh (without boundary)

Csaszar Torus
preview

A polyhedral torus where every pair of vertices is connected by an edge. This surface was originally described by Ákos Császár in the paper "A Polyhedron without Diagonals," Acta Sci. Math (1949). While there are several versions of this surface floating around on the web, none of them seem to agree with the description given in the paper (and some are not even embedded!). Part of the issue, perhaps, is that the original paper seems to be available only as a noisy, low-resolution scan. The archive below contains a carefully-checked reproduction of the original paper, as well as a mesh where vertex coordinates and indices correspond exactly to the original values. Note however that the paper does not describe an oriented polyhedron—the archive hence contains both the original polyhedron and an oriented version.

The archive contains:

  • the original Csaszar torus
  • an oriented version of the Csaszar torus
  • a scan of the original paper
  • TeX source for a reproduction of the paper
  • a PDF version of the reproduced paper

Copyright on the original paper has expired past any possible extension; it is now in the public domain. I hereby release all other materials into the public domain.
Tilings
preview

This archive contains meshes of all of the regular and semi-regular tilings of the plane. Here a "regular" tiling is one consisting of only a single regular polygon. A "semi-regular" tiling may include more than one type of polygon, but every vertex will look identical.

The archive includes:

  • meshes of the three regular tilings
  • meshes of the eight semi-regular tilings
  • the C source used to generate these meshes

Each mesh contains roughly two thousand faces. The source can be used to generate tilings with more faces.
