Differential Rendering of Unorganized Points

Rendering of Unorganized Points with Octagonal Splats

Point sets from range scanners are noisy and do not contain additional data such as normals, which makes it difficult to create a mesh for rendering. We use the moving least-squares (MLS) approximation to get normals and differential information, and approximate the surface near each point by an MLS surface. From this we obtain a splat of a new octagonal shape which approximates the local curva...

Direct Reconstruction of a Displaced Subdivision Surface from Unorganized Points

In this paper we describe the generation of a displaced subdivision surface directly from a set of unorganized points. The displaced subdivision surface is an efficient mesh representation that defines a detailed mesh with a displacement map over a smooth domain surface, and has many benefits including compression, rendering, and animation, which overcome limitations of an irregular mesh produc...

Reconstruction and Rendering of Implicit Surfaces from Large Unorganized Point Sets

The displaced subdivision surface reconstruction from unorganized points

In this paper we propose a new mesh reconstruction scheme that produces a displaced subdivision surface directly from unorganized points. The displaced subdivision surface is a new mesh representation that defines a detailed mesh with a displacement map over a smooth domain surface, but original displaced subdivision surface algorithm needs an explicit polygonal mesh since it is not a mesh reco...

Orienting unorganized points for surface reconstruction

We address the problem of assigning consistently oriented normal vectors to unorganized point cloud with noises, non-uniformities, and thinsharp features as a pre-processing step to surface reconstruction. The conventional orienting scheme using minimal spanning tree fails on points with the above defects. Different from the recently developed consolidation technique, our approach does not modi...
