AutoShade was an early 3D rendering package for use with AutoCAD. Autodesk developed Autoshade in 1987. It became obsolete after the release of Autodesk's 3D Studio.

AutoCAD commercial computer-aided design (CAD) and drafting software application

AutoCAD is a commercial computer-aided design (CAD) and drafting software application. Developed and marketed by Autodesk, AutoCAD was first released in December 1982 as a desktop app running on microcomputers with internal graphics controllers. Before AutoCAD was introduced, most commercial CAD programs ran on mainframe computers or minicomputers, with each CAD operator (user) working at a separate graphics terminal. Since 2010, AutoCAD was released as a mobile- and web app as well, marketed as AutoCAD 360.

Description

AutoShade was a DOS application. Autodesk developed it to produce realistic shaded renderings of 3D face objects made by their CAD program, AutoCAD. It simulated various types of lightsspot, point, and infinite directional. To create a rendering, a person:

DOS group of closely-related PC-compatible operating systems

DOS is a platform-independent acronym for disk operating system which became common shorthand for the popular family of disk operating systems for x86-based IBM PC compatibles. DOS primarily consists of Microsoft's MS-DOS and a rebranded IBM version under the name PC DOS, both of which were introduced in 1981. Later compatible systems from other manufacturers include DR DOS, ROM-DOS, PTS-DOS, Embedded DOS as well as FreeDOS (1998) and RxDOS. MS-DOS dominated the IBM PC compatible market between 1981 and 1995.

Computer-aided design constructing a product by means of computer

Computer-aided design (CAD) is the use of computers to aid in the creation, modification, analysis, or optimization of a design. CAD software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. The term CADD is also used.

AutoLISP is a dialect of the programming language Lisp built specifically for use with the full version of AutoCAD and its derivatives, which include AutoCAD Map 3D, AutoCAD Architecture and AutoCAD Mechanical. Neither the application programming interface (API) nor the interpreter to execute AutoLISP code are included in the AutoCAD LT product line.

Files

AutoShade wrote the rendering to an .RND file. In the first version, the .RND file was a 2D vector file, importable into applications such as Adobe Illustrator version 4. Later, when Autodesk added Gouraud shading, the .RND could also be a raster file.

Vector graphics type of 2D digital illustration that uses geometric and styling definitions to represent images

Vector graphics are computer graphics images that are defined in terms of 2D points, which are connected by lines and curves to form polygons and other shapes. Each of these points has a definite position on the x- and y-axis of the work plane and determines the direction of the path; further, each path may have various properties including values for stroke color, shape, curve, thickness, and fill. Vector graphics are commonly found today in the SVG, EPS and PDF graphic file formats and are intrinsically different from the more common raster graphics file formats of JPEG, PNG, APNG, GIF, and MPEG4.

Adobe Illustrator vector graphics editor developed and marketed by Adobe Systems

Adobe Illustrator is a vector graphics editor developed and marketed by Adobe Inc. Originally designed for the Apple Macintosh, development of Adobe Illustrator began in 1985. Along with Creative Cloud, Illustrator CC was released. The latest version, Illustrator CC 2019, was released in October 2018 and is the 23rd generation in the product line. Adobe Illustrator was reviewed as the best vector graphics editing program in 2018 by PC Magazine.

Gouraud shading shading algorithm invented by the computer scientist Henri Gouraud

Gouraud shading, named after Henri Gouraud, is an interpolation method used in computer graphics to produce continuous shading of surfaces represented by polygon meshes. In practice, Gouraud shading is most often used to achieve continuous lighting on triangle surfaces by computing the lighting at the corners of each triangle and linearly interpolating the resulting colours for each pixel covered by the triangle. Gouraud first published the technique in 1971.

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.

Autodesk Animator software

Autodesk Animator, also known as Ani Pro, PJ Paint, PJ, was a 2D computer animation and painting program in 1989 for PC with MS-DOS. The program was considered to be groundbreaking in the field of computer animation when it was initially released, and was very popular in the late 1980s and the early 1990s.

Demise

Though the final version of AutoShade supported RenderMan extensions, Autodesk never developed it into a full rendering application. Even with AutoFlix, it did not support keyframing or hierarchical kinematics. When Autodesk released 3D Studio, the need for AutoShade ended, since 3D Studio was far superior in technology and in ease of use.

Design Web Format (DWF) is a secure file format developed by Autodesk for the efficient distribution and communication of rich design data to anyone who needs to view, review, or print design files. Because DWF files are highly compressed, they are smaller and faster to transmit than design files, without the overhead associated with complex CAD drawings. With DWF functionality, publishers of design data can limit the specific design data and plot styles to only what they want recipients to see and can publish multisheet drawing sets from multiple AutoCAD drawings in a single DWF file. They can also publish 3D models from most Autodesk design applications.
