A Collection of Meshes for Simulation.

Sim Mesh

Common computer graphics meshes that are (trying to be):

1. Simulation ready.
2. Centered at the origin.
3. Scaled to a unit box.
4. Heading +Y and facing +Z (default camera can be looking at (0,0,0) from (1,1,1)).
5. Small to medium file size.

Gallery

We provide several representations:

• Triangle Mesh
  • Tri-1: Fine triangle mesh with ~100k faces (or textured mesh); Tri-2: Coarse triangle mesh with ~5k faces.
  • .ply for both. .obj and .png for textured mesh.
• Tetrahedral Mesh
  • Tet-1: Fine tetrahedral mesh with 0.01 edge length; Tet-2: Coarse tetrahedral mesh with 0.05 edge length.
  • .npz for both. np.load(f)['verts'] and np.load(f)['elems'] for vertices and elements respectively.
• Point Cloud
  • PCD-1: Fine point cloud with ~100k points; PCD-2: Coarse point cloud with ~10k points.
  • .ply for both.
• More to come...
