Fast developments in computer technology have given rise to different application
areas such as multimedia, computer games, and Virtual Reality. All these
application areas are based on animation of 3D models of real world objects. For
this purpose, many tools have been developed to enable computer modeling and
animation. Yet, most of these tools require a certain amount of experience about
geometric modeling and animation principles, which creates a handicap for inexperienced
users. This thesis introduces a solution to this problem by presenting
a mesh animation system targeted specially for novice users. The main approach
is based on one of the fundamental model representation concepts, Laplacian
framework, which is successfully used in model editing applications. The solution
presented perceives a model as a combination of smaller salient parts and uses
the Laplacian framework to allow these parts to be manipulated simultaneously
to produce a sense of movement. The interaction techniques developed enable
users to carry manipulation and global transformation actions at the same time to
create more pleasing results. Furthermore, the approach utilizes the multi-touch
screen technology and direct manipulation principles to increase the usability of
the system. The methods described are experimented by creating simple animations
with several 3D models; which demonstrates the advantages of the proposed
solution.
