TLDR

An implementation is demonstrated that is able to align two range images in a few tens of milliseconds, assuming a good initial guess, and has potential application to real-time 3D model acquisition and model-based tracking.Expand

The limitations of canonical alignment are described and an alternate method, based on spherical harmonics, for obtaining rotation invariant representations is discussed, which reduces the dimensionality of the descriptor, providing a more compact representation, which in turn makes comparing two models more efficient.Expand

A hardware and software system for digitizing the shape and color of large fragile objects under non-laboratory conditions and the largest single dataset is of the David - 2 billion polygons and 7,000 color images.Expand

This work describes a system for representing and progressively displaying meshes that combines a multiresolution hierarchy based on bounding spheres with a rendering system based on points, which is suitable for large data sets.Expand

A non-photorealistic rendering system that conveys shape using lines, and shows that suggestive contours can be drawn consistently with true contours, because they anticipate and extend them.Expand

A finite-differences approach for estimating curvatures on irregular triangle meshes that may be thought of as an extension of a common method for estimating per-vertex normals is presented, which results in significantly fewer outlier estimates while more broadly offering accuracy comparable to existing methods.Expand

A new 3D model acquisition system that permits the user to rotate an object by hand and see a continuously-updated model as the object is scanned, demonstrating the ability of the prototype to scan objects faster and with greater ease than conventional model acquisition pipelines.Expand

A method for detecting uncertainty in pose is described, and a point selection strategy for ICP is proposed that minimizes this uncertainty by choosing samples that constrain potentially unstable transformations.Expand

A reparameterization of the BRDF is proposed as a function of the halfangle and a difference angle instead of the usual parameterization in terms of angles of incidence and reflection, which reduces storage requirements for a large class of BRDFs.Expand

Range scanning, manual 3D editing, and other modeling approaches can provide information about the geometry of surfaces in the form of either 3D positions (e.g., triangle meshes or range images) or… Expand
