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 these models are not ideal for testing the robustness of some algorithms since they're noise-free and perfectly manifold—compare with the models available from the Stanford 3D Scanning Repository and the AIM@Shape Project.

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
preview

An abstract city. The archive contains:

  • a polygonal mesh of the city
  • a triangulated mesh of the city
  • a mesh of a ground plane
  • baked indirect and environment-based lighting

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.
