Enclosure Sphere Based Cell Visibility for Virtual Endoscopy
Virtual Endoscopy is an interactive exploration inside human organs to detect polyps by combining medical imaging and computer graphics technologies. In order to realize rendering acceleration, we present a novel two-steps visibility algorithm, Enclosure Sphere Based Cell Visibility (ESBCV), which performs visibility computation between cells assisted by Z-buffer in preprocessing and eye-to-cell visibility through a simple numerical calculation of the intersection of a circle with the rendered image in navigation. Experimental results demonstrated virtual navigation with high image quality and interactive rendering speed. CR
