2.3 LITERATURE REVIEW

While control theory is a mature field of study developed after the industrial revolu-
tion, the adoption of the techniques in the domain of computer software, particularly
real-time computer graphics systems, remains nascent. This literature review pro-
vides a survey of research in these areas as background for our research.

2.3.1 c omPaRatiVe s tudy on e xisting R eseaRch
The premise of the novelty in our research is founded upon close examination of
previous work done in the fields of both real-time computer graphics and control
theory, particularly those that have been successful in fusing the two disciplines and
a careful thought process in terms of innovation in this area. A broad-stroke but sys-
tematic and progressive approach was taken to consider research publications within
two decades to ensure that relevant techniques are not missed out regardless of their
age and how they might contribute to further knowledge development.
Figure 2.7 shows the research comparative study flow conducted in this work
which consists of the Classification Stage and the Qualitative Comparison Stage.
In the Classification Stage, we begin with the most relevant keywords in the litera-
ture search terms. We consider the following words as the “lowest denomination”
