![]() ![]() Those are flat displays that use binocular disparity or linear perspective to make objects appear three- dimensional when in fact they only have height and width and lack a true volume profile. A scientist's dream of 3- D projections like those he saw years ago in a Star Wars movie has led to new technology for making animated 3- D table- top objects by structuring light. Wherever the UV light intersects with the green light it generates a 3- dimensional image inside the chamber. The two project patterns of light into a chamber of photoactivatable dye. The set- up for the SMU 3- D light pad includes this ultraviolet projector as well as a visible projector. ![]() Chemistry discovery yields 3- D table- top objects crafted from light.
