Mesh
Compression for Graphics: Theory and Practice Progressive
Coders/Decoders
With the development of 3D geometry as a new multimedia
data type, compression of large meshes is becoming a crucial
subject of research. Efficient compression allows for fast
transmission of 3D data in many applications, ranging from
collaborative design to catalogs. This tutorial will present
past and present methods used to encode meshes. We will
discuss connectivity and geometry compression, for both
single resolution or progressive transmission. We will intertwine
practice and theory, to clearly show what are the current
challenges in this field.

One
of the central subjects in computer graphics is the accurate
rendering of virtual scenes. This includes visually accurate
computation of the equilibrium distribution of light in
a scene given the geometry, its reflectance properties,
and the light sources. The mathematical formulation of this
problem, under the assumption of geometric optics, leads
to a transport equation which is given by a 2nd kind Fredholm
integral equation. Such equations also appear in classical
radiative transport. In this tutorial section I will describe
the problem setup in detail and review possible solution
approaches before focusing in more detail on finite element
based algorithms. The best finite element algorithms for
this problem are based on hierarchical (wavelet) methods
and I will discuss these in detail.
