Since the models are 3 dimensional, the background is 2 dimensional, through computer simulation, Lorentz contraction, Taylor expansion, and Fourier transformation, the final product came out to be 2.5 dimentional, which is 2.5D
Another way to express it with simple algebra is (3D +2D)/2 = 2.5D
All scientific analysis seems to support the 2.5D theory

exit this crap
