By producing "6-D" images, an MIT professor and colleagues are creating unusually realistic pictures that not only have a full three-dimensional appearance, but also respond to their environment, producing natural shadows and highlights depending on the direction and intensity of the illumination around them.The process can also be used to create images that change over time as the illumination changes, resulting in animated pictures that move just from changes in the sun's position.
