teapot pool glass tile glass mosaic amber cuboctahedron bumpy sphere straight-line approximation Figure 1 : The bending and focusing of light in refractive media creates distinctive rich details. The top row shows single scatter surface caustics in glass and water. The bottom row shows complex volumetric refractive caustics in amber and glass. All images were generated using the method in this paper, except the bottom right which used the common straight-line approximation that neglects shadowdoi:10.1145/1576246.1531398 fatcat:fdturd24jbemlbdagrrkhvn6f4
