An improved volume rendering algorithm based on voxel segmentation

Volume rendering could display the image in an integrated distribution of a variety of substances. It is convenient to view the body data for a doctor. Volume rendering should traverse each voxel of the data, causing large calculation and slow image generation, and can not change the external light and perspective. It is need to start the drawing again when parameters have changed. The complex process lead the slow speed of rebuilt. In this paper, volume rendering algorithm based on segmentation in three-dimensional reconstruction is present, including the segmentation of CT data, the normal vector of the volume element, and the generation of the final image. This method greatly accelerated the speed of rendering image, and improves image display quality. Also, it can well reflect the global status of three-dimensional data.
