摘要

texture memory for storing a plurality of two-dimensional or two-dimensional slices slicing texture , and volume data ; Performing a two-dimensional two-dimensional texture map into a texture , and the texture mapping unit for performing a plurality of two-dimensional texture sampling in a two-dimensional slice ; And by including a processor, a two-dimensional operation using the sampled value of the texture sampling for performing volume rendering , it is possible to improve the speed of the rendering process , even when performing a three-dimensional volume rendering in a graphics processing unit that does not support texture mapping function . ;
