Demo of the main result: from top to bottom, the same "Lucy" model rendered with two types of translucent materials specified by two different Phase Functsion with other material paraemeters fixed. From left to right, "Lucy" with the same translucent material rendered with three lighting directsions. LIghting directions have different effects on different materials

Here are the parameters used to specify the images used in the Lucy experiment, the corresponding target images
