Dark Art: Making 3D Shadow Puppets
In this episode of NPR's Science Friday, Rockefeller University PhD student Tom McDonagh shows off his latest shadow puppet production: the true story of an American doctor and French inventor who took to the skies in a hydrogen balloon and made the first trip by air across the English Channel. But McDonagh has done something amazing with shadow puppetry. By manipulating the sharpness and intensity of his halogen light source, McDonagh and his fellow puppeteers are able to simulate cinematic zooms and pans in real-time animation. And then by using two polarized light sources, he can give that animation a 3D effect for viewers wearing standard polarized 3D glasses. Amazing!
