abstract = "Generating computer animation involves two interwoven
components. The first component is the set of tools
(tools) used to generate and render computer animation.
Tools consist of software and hardware that allow the
creation of abstract geometric models, modification of
these models over time, as well as their rendering. The
second component is the sequence of instructions to be
carried out by the software and hardware tools, to
generate and render a specific animation sequence, here
referred to as an execution plan or execution.
Execution usually resides in the thoughts, story-boards
and drawings of the director and animators that have to
carry out the task of creating a specific sequence.
Most modern software and hardware focus on the creation
of tools that allow for the generation and rendering of
realistic looking models and motion. Modeling and
rendering tools are very important as they provide the
materials used by the computer animator. Novel
tools/materials often create new avenues for visual
exploration. However, the quality of an animation
sequence depends equally on the quality of the work
carried out by the director and animators in terms of
using the tools available, i.e. the quality of
execution.",
