Spectral Watertight Surface Reconstruction
An eigenvector-based method for reconstructing a watertight surface from point-cloud data. This spectral method is particularly effective for noisy and undersampled point sets, because decisions about the reconstructed surface are based on a global view of the model.

Automated Meshing of Sparse 3D Point Clouds
A novel method using simulated annealing to create an optimal surface mesh by selecting a subset and triangulation of a point cloud that reliably represents the actual scene topology.

Casual 3D Photography
A lightweight, point-and-shoot 3D camera for reconstruction of smooth surfaces. The approach extracts 3D shape from a single image and is completely automatic.
