Title:


    Slanting Shadow: Changing Invisible Shadow Shapes by Rotation for Expanding Shadowgraph Experience

Description:


    This paper proposes a method for hiding information inside an actual object and viewing the hidden information as shadows selectively by rotating the object. Our proposed system creates shadows using the properties of polarizing plates and 1/2 wavelength boards. The goal of our research is to develop a novel method for creating extended shadows.
