Developer's DescriptionBy Bion Smalley & AssociatesTransfer anamorphic 3D illusions onto sidewalks or other surfaces using chalk or other media.BSAsidewalk3D creates easy-to-use grids for copying anamorphic projections of images onto sidewalks or other surfaces. The result, when viewed from the correct observation point, is a 3D illusion that appears to be a (usually large) object or scene. To create an anamorphic illusion: 1. Load an image into BSAsidewalk3D. 2. Set the observation point dials and anamorphic projection size dials. 3. Select the size of the grid squares, from 6 inches to 4 feet. 4. Create and print the grid. 5. Use the grid as a guide to lay out and render the image on a surface. Complete documentation leads the user step-by-step through the process. Also available is an option to print a "flat" grid for creating murals.
