With two cameras set about 10 inches apart at the top of the rover's remote sensing mast, Mastcam-Z can produce a 3D image to be viewed with 3D glasses. This is similar to the way our two human eyes work, with our brain forming the 3D image, but no glasses needed! This stereo, or 3D, image was taken with the Mastcam-Z simulator system, used during testing at Arizona State University. https://photojournal.jpl.nasa.gov/catalog/PIA24196
