Figure 15
Model and resulting absorption correction created by the superposition of two images of Perlin noise with different gradient grids. The finer gradient grid has a node distance of μln = 0.2 and μRpv = 0.5 while the long-range grid has a node distance of μln = 2 and Rpv = 0.2. The voxel size of the model is μd = 0.01. The absorption correction of the combined surface shows features observed for the purely rough and purely wavy surface.
