Compression of Dynamic 3D Meshes and Progressive Displaying

Generating and Displaying Progressive Meshes

Triangle meshes are a common representation for geometric shapes in computer graphics. However, limited transmission bandwidth disables quick preview of detailed models when represented in standard formats. In this paper, we validate the Progressive Mesh (PM) representation as a compact , lossless, and hierarchical format that enables a broad range of applications, for example , mesh reduction ...

Compression of 3D triangular meshes with progressive precision

Combined compression and simplification of dynamic 3D meshes

We present a new approach to dynamic mesh compression, which combines compression with simplification to achieve improved compression results, a natural support for incremental transmission and level of detail. The algorithm allows fast progressive transmission of dynamic 3D content. Our scheme exploits both temporal and spatial coherency of the input data, and is especially efficient for the c...

Progressive Geometry Compression for Meshes

A novel progressive geometry compression scheme is presented in the paper. In this scheme a mesh is represented as a base mesh followed by some groups of vertex split operations using an improved simplification method, in which each level of the mesh can be refined into the next level by carrying out a group of vertex split operations in any order. Consequently, the PM representation can be eff...

Temporal DCT-Based Compression of 3D Dynamic Meshes

This paper introduces a new compression scheme for 3D dynamic meshes with constant connectivity and time-varying geometry. The proposed approach, referred to as Temporal-DCT encoder (TDCT), combines a piecewise affine prediction scheme with a temporal DCT-based compression of the prediction errors. Experiments show that TDCT achieves up to 70% and 54% lower compression distortions than the GV a...
