Outline
A discretely sampled object representation (DSOR) is a schematic representation of data obtained by a sampling
process, which takes a collection of samples at discrete positions in space in order to capture certain geometrical
and physical properties of one or more objects of interest. Examples of DSORs include images, videos, volume
data sets and point data sets. Unlike many commonly used data representations in computer graphics, DSORs
lack in geometrical, topological and semantic information, which is much needed for controlling deformation and
animation. Hence it poses a significant scientific and technical challenge to develop deformation and animation
methods that operate upon DSORs. Such methods can enable computer graphics and computer animation to
benefit enormously from the advances of digital imaging technology.
In this state of the art report, we survey a wide range of techniques that have been developed for manipulating, deforming and animating DSORs. We consider their operability in the context of elementary manipulation,
controllability in the context of deformation, and modellability in the context of animation.
