Boxshot invites users to upload their book cover and spine, then fiddle with a variety of controls to arrive at a striking 3D rendering of said cover. The basic offering is free, with a paid version offering more bells and whistles.
“This 3D book cover generator is constantly rendering a realistic book model with the pictures you loaded. Every time you move the camera or change a parameter — the rendering starts from the beginning. It may take some time for the noise to come away and you get a nice and clear 3D image.”
