Abstract


Visual analysis of an important means of dealing with large and complex data field , has become an indispensable tool of scientific research , engineering , and other fields . Direct volume rendering method can reflect the overall distribution of the data field , and thus become the most important one of the volume data rendering method . However, since the data exists between the obscuration problem , only by adjusting the transfer function is difficult to reveal the internal details of the characteristics of the data field . Body cuts technology can play a very good supplement to the transfer function , important to reveal the internal details of the characteristics of the data field . This paper conducted a systematic study on the body cuts technology thesis include : ( 1) comprehensive research the body laid off techniques, methods , through the analysis of the advantages and disadvantages of the various methods , the research content - GPU - based body of any reduction technology . (2) because technology cuts based on the reduction of the texture of the body has a flexible, convenient features , this study is based on the reduction of texture to achieve any of the three-dimensional volume data clipping technology . In order to achieve this technique , the first study of the reduction of the texture of the algorithm based on the reduction of the geometric model generation , then any cuts based on the reduction of the texture on the GPU . ( 3) In order to overcome the contradictions between the reduction of texture and limited texture memory , the paper proposes the concept of multi-resolution texture build a multi-resolution texture and reduction of texture -based multi-resolution arbitrary cuts technology . (4 ) expansion mainstream visualization package VTK proposed algorithm embedded VTK, VTK developed based on the extended integrated visualization platform software SVIP achieved good results .
