Imagine was a cutting edge 3D modeling and raytracing program, originally for the Amiga computer and later also for MSDOS and Microsoft Windows.

It used the .iob extension for its objects. Imagine was a derivative of the software Turbo Silver, which was also for the Amiga and written by Impulse. The Windows version of the program was abandoned when Impulse dropped out of the 3D software market; but the Amiga version is now maintained and sold by CAD Technologies
