Problem – 2.5D

SLIDE 5

Problem – 3D

Conventional display are view-independent

Pixel intensity/color does not vary as a function of viewing angle

SLIDE 6

Problem – 3D

Light Field display are view-dependent (automultiscopic)

Achieved with pinhole/lenslet array placed close to the display
Trades decreased spatial resolution for increased angular resolution
