==Method==
# Create a low-resolution 3D grid with axis (x, y, intensity).  
#* For an 8MP image, they claim a \(70 \times 70 \times 10\) grid is sufficient.
#* This is called a ''bilateral grid''.  
# Place pixels for your 2D image into bins within the bilateral grid based on x, y position and intensity.
# When performing image effects, only change pixels within ''slices'' of the grid: pixels within a certain intensity.
