Abstract :
As the most popular tablet computer, iPad is designed for audio-visual media, entertainment, and a variety of applications. However, because of the limited memory resource, it´s difficult to implement volume rendering algorithm on iPad. Volume rendering directly displays stereoscopic images from 3D data set, so it is widely used in the field of biology and medicine. In this paper, an optimized Maximum Intensity Projection (MIP) volume rendering algorithm is proposed to reduce resource usage significantly. Four clusters of viewpoints are used to optimize the cell removal process. Twice scans in opposite directions are performed for each cluster of viewpoints to remove the useless cells thoroughly, thus to reduce the memory cost. Based on the optimized algorithm, an interactive 3D image processing system for iPad is implemented.
