Description: This thesis presents a method for reconstructing the shape of specular, transparent objects from multiple viewpoints. This method works on scenes where light refracts through the object twice, entering and exiting the object's surface. Scenes are reconstructed by determining the 3D path light takes through each pixel on a camera's image plane. Triangulating this light path is accomplished by finding the one that is consistent with known light rays from multiple viewpoints of the scene, determined using an environment-matting based approach. It is shown that this method requires at least three viewpoints to triangulate light paths in general, four if the index of refraction is unknown. Also, shapes and camera configurations for which light-path triangulation fails regardless of the number of viewpoints are explored. Results of our method applied to several glass objects are analyzed.
