Ray Casting for Iso-surface in Volumetric Data

Volume data visualization is an active field of research and development. It can be
applied in many areas such as medical, oil and gas exploration, etc... Although volume
visualization is highly computational cost, there is a vision of real time volumetric
visualization systems based on interactive ray tracing. Over the years, many rendering
algorithms have been created and enhanced. The focus of this project is to develop a
simple ray casting program for volumetric data. The program will be able to render
specific volume data using a single processor in a reasonable amount of time. It is opento
improve for implementation on multiprocessors. The thesis will compare some existing
algorithms for ray casting in terms of image quality, computing time, complexity and so
forth. The thesis includes a proposal of new multisampling algorithm, which significantly
reduces rendering time while producing similar quality of image with existing algorithms.
