  In the last years, Distributed Visualization over Personal Computer (PC)
clusters has become important for research and industrial communities. They
have made large-scale visualizations practical and more accessible. In this
work we survey Distributed Visualization techniques aiming at compiling last
decade's literature on the use of PC clusters as suitable alternatives to
high-end workstations. We review the topic by defining basic concepts,
enumerating system requirements and implementation challenges, and presenting
up-to-date methodologies. Our work fulfills the needs of newcomers and seasoned
professionals as an introductory compilation at the same time that it can help
experienced personnel by organizing ideas.
