Terrestrial laser scanning (TLS) is a ground-based approach to rapidly acquire 3D point
clouds via Light Detection and Ranging (LiDAR) technologies. Quantifying tree-scale …

Commercial buildings as well as residential houses represent core structures of any modern
day urban or semiurban areas. Consequently, 3-D models of urban buildings are of …

In theory, efficient and high-quality rendering of unstructured data should greatly benefit from
modern GPUs, but in practice, GPUs are often limited by the large amount of memory that …

Unstructured meshes are characterized by data points irregularly distributed in the Euclidian
space. Due to the irregular nature of these data, computing connectivity information between …

Volume data these days is usually massive in terms of its topology, multiple fields, or
temporal component. With the gap between compute and memory performance widening …

We propose a family of spatial data structures for the representation and processing of
Triangulated Irregular Networks (TINs). We call such data structures Terrain trees. A Terrain …

A common first step in the terrain processing pipeline of large Triangulated Irregular
Networks (TINs) is simplifying the TIN to make it manageable for further processing. The …

Unstructured data are collections of points with irregular topology, often represented through
simplicial meshes, such as triangle and tetrahedral meshes. Whenever possible such …

We address the problem of performing a topology-aware simplification algorithm on a
compact and distributed data structure for triangle meshes, the Terrain trees. Topology …

We describe a concise representation for adaptive diamond-kite meshes based solely on
the vertices and their stars. The representation is exact because it uses only integers, is …
