Anaglyph of an Lunar Reconnaissance Orbiter Camera (LROC) Wide Angle Camera (WAC) mosaic of the lunar nearside taken at low-Sun conditions. You will need 3D stereo glasses to see it pop off your screen! The two perspectives that make up this anaglyph were generated by draping the same low-Sun WAC mosaic of the lunar nearside over the Global Lunar DTM (Digital Terrain Model) 100 m topographic model (GLD100) with two different sub-Earth points. Planetary scientists use anaglyphs to visualize the 3D structure of planetary surfaces. For example, the HiRISE team has over three thousand anaglyphs of the Martian terrain available for scientific study and public use. This type of visualization is helpful with the intuitive and qualitative interpretation of a scene by revealing geologic relationships that are not obvious from a single 2D image.
