VARIABLE SPLATTING FOR VOLUME RENDERING
Wang Wen-chen · Chinese Journal of Computers · 1997
As an important method of the projection approach, splatting is very successful in rendering regular volume data. However, it requires that the size and shape of voxels be constant. This prerequirement hinders the method from its application in volume rendering of irregular or curvilinear data. Since the size and shape of voxels vary greatly in curvilinear or irregular volumes, complicated calculations are required in rendering those data, which severely limits the efficiency of volume rendering. This paper presents an algorithm using footprints variably to extend splatting methods in rendering irregular volumes and curvilinear volumes. The experiments show that the proposed method is quite effective.
