Figure 1: All images show 3D texture based volume rendering of the engine data set.On the left, the data set is displayed with full resolution.In the middle, two different levels of detail are used with lower resolution in the back.This reduces texture memory consumption to 57%.On the right, the adaptive representation using four levels of detail from front-to-back requires only 29% of the original texture memory.Here, the data set was rendered with only 32% of the originally needed number of texture lookups.
