Abstract: With development of biotechnology and medical techniques, large scale volume data sets that cannot be achieved in local hard disk are produced for research purpose. In this project, I surveyed on various volume rendering schemes including two steps, data preprocessing and fast volume rendering algorithm, which compress and extract required data for rendering. Two progressive transmission/rendering schemes using wavelet foveation are implemented and compared in this project, Region-Based and Coarse-To-Finer. Region-Based scheme transmits and renders the fovea requested by the user on the client site at highest resolution first, and iteratively expands the fovea layer by layer towards the peripheral. While Coarse-To-Finer gives a rough preview image at low resolution in a short time at the client site and progressively refines the fovea from peripheral to the fovea center.
