3D meshes are commonly used to represent virtual surface and volumes. However, their raw
data representations take a large amount of space. Hence, 3D mesh compression has been …

Three-dimensional (3D) meshes have been widely used in graphic applications for the
representation of 3D objects. They often require a huge amount of data for storage and/or …

We show how spectral methods may be applied to 3D mesh data to obtain compact
representations. This is achieved by projecting the mesh geometry onto an orthonormal …

In this paper, we propose a generic point cloud encoder that provides a unified framework
for compressing different attributes of point samples corresponding to 3D objects with an …

Efficient algorithms for compressing geometric data have been widely developed in the
recent years, but they are mainly designed for closed polyhedral surfaces which are …

A new progressive lossless 3D triangular mesh encoder is proposed in this work, which can
encode any 3D triangular mesh with an arbitrary topological structure. Given a mesh, the …

WebGIS (also known as web‐based GIS and Internet GIS) denotes a type of Geographic
Information System (GIS), whose client is implemented in a Web browser. WebGISs have …

Within distributed computing environments, access to very large geospatial datasets often
suffers from slow or unreliable network connections. To allow users to start working with a …

We propose a generic point cloud encoder that compresses geometry data including
positions and normals of point samples corresponding to 3D objects with arbitrary topology …

This paper presents a new algorithm for the lossy compression of scalar data defined on 2D
or 3D regular grids, with topological control. Certain techniques allow users to control the …
