Global Non-Rigid Alignment of 3D Scans

A new pipeline for non-rigid global registration of large, high-resolution 3D scanned data sets. This reduces visible misalignment artifacts such as tearing and blurring of detail.

Parameterization-Free Projection for Geometry Reconstruction

This paper introduces a locally optimal projection operator for surface reconstruction. The operator is parameterization-free, so it can deal with complex geometry and high noise level.

Algebraic Point Set Surfaces

An efficient and robust surface representation based on spherical fit that allows handling of complex, low-sampled, point-based models. A normal evaluation procedure and sharp features are also included.

Direct Visibility of Point Sets

This paper proposes a simple operator for determining the visible points in a point cloud, as viewed from a given viewpoint. Visibility is determined without reconstructing a surface or estimating normals.
