Body drawing visible method based on fractal

Abstract

One volume rendering visualization method based on elementary theory belongs to computer application technology field. Basing on elementary theory, transform the body data into three-dimensional elementary coefficient through three-dimensional elementary transform, and project three-dimensional elementary coefficient to get the projected two-dimensional elementary coefficient according to the appointed visual angle, then carry two-dimensional inverse transform to the two-dimensional elementary coefficient to get the final protracting image. It effectively enhances the volume rendering speed and gets better draw effect after four times iterative in common. It has faster dispose speed with better draw effect for the visualization with a lot of data. Because the elementary volume rendering process is the iterative process, the production of image can take in step by step and the elementary volume rendering sustains the stepwise exaltation mechanism and it is fit for the need of hardware resource and network visualization.

Description

technical field [0001] The invention relates to a method in the field of computer application technology, in particular to a volume rendering visualization method based on fractal theory. Background technique [0002] Since the 1980s, with the rapid development of imaging technology, especially the gradual maturity of medical imaging technology, a large amount of volume data has emerged. How to effectively use these data is a major problem for researchers. Most of the data today can only be processed through visual means. The scientific visualization method is used to reconstruct a three-dimensional shape from a two-dimensional image sequence, which can make up for the lack of imaging equipment, provide users with realistic three-dimensional graphics, and facilitate users to observe and analyze from multiple angles and levels. It has great practical value in clinical diagnosis, operation planning and medical teaching. In recent years, volume rendering methods, as a scienti...
