application. Autodesk developed it to produce realistic shaded renderings of 3D face objects made by their CAD program, AutoCAD. It simulated various types of lights—spot, point, and infinite directional. To create a rendering, a person: * Made an AutoCAD Drawing file containing 3D faces * Placed AutoShade light and camera blocks * Used an AutoShade-provided

Files

AutoShade wrote the rendering to an .RND file. In the first version, the .RND file was a 2D

, the .RND could also be a raster file. Autodesk developed an application called Flimaker for MS-DOS, which converted .RND files into a format usable in Autodesk Animator. This could be used, in conjunction with AutoFlix, to create rudimentary 3D animations from AutoCAD source material.
