Shepard and Metzler 3D Objects

(.zip archive) The famous Shepard & Metzler (1971) 3D object set. Roger Shepard gave me xeroxes of the original set that he distributed. We have scanned the images in at 300dpi. Included is the original "readme" file by Roger explaining the organization of the set. Beyond still being useful for research, these objects hold a place as perhaps the first computer-generated complex stimulus set used in visual psychophysics. All of us owe a huge debt to Roger. Graham Dean has also kindly provided the Shepard & Metzler objects as 3D models (in DXF format). Be sure to read his README.TXT. Shepard, R. N., & Metzler, J. (1971). Mental Rotation of three-dimensional objects. Science, 171, 701-703.
