Research and Realization of a Volume Rendering Algorithm Based on Shear-Warp Volume Rendering Algorithm

After analyzing the characteristics of virtual endoscopy and volume data visualization, this paper proposes an improved volume rendering algorithm based on interactive dynamic volume rendering algorithm of perspective project volume rendering, which improves the volume rendering speed in the 3D data field of the virtual endoscopy. This algorithm adopts the dynamic data reduction technique. It automatically generates the navigation path at great speed. It also creates virtual endoscopy images helping doctors for diagnosis. The virtual endoscopy system by the computer based on the volume rendering verifies the real time and generation image quality of this algorithm.
