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

Vector most often refers to:
* Euclidean vector, a quantity with a magnitude and a direction
* Disease vector, an agent that carries and transmits an infectious pathogen into another living organism
Vector may also refer to:

, 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.
