Graphics`ThreeScript`
3-Script is a file format for transferring descriptions of three-dimensional graphics objects from Mathematica to other programs. All Mathematica kernels have the ability to render three-dimensional images into the PostScript page description language. For certain applications, it is desirable to have a description of the image that retains the three-dimensional character that is lost when rendering into PostScript. The package Graphics`ThreeScript` supplies a number of utilities for writing suitable Mathematica objects into 3-Script format files.
This loads the package.
In[1]:= <<Graphics`ThreeScript`
This constructs a Graphics3D object.
In[2]:= obj = Graphics3D[ Polygon[{{0,0,0}, {0,1,0}, {0,1,1}}]]
Out[2]= 
This writes the 3-Script format into the file object.ts. Note that the filename is returned.
In[3]:= ThreeScript[ "object.ts", obj]
Out[3]= 
This shows the contents of the file.
In[4]:= !!object.ts

The 3-Script format works with all three-dimensional primitives and directives. This includes both Graphics3D and SurfaceGraphics objects. Note that in the 3-Script format information such as coordinates appears below the command name.

Standard 3-Script descriptions of three-dimensional objects.

3-Script commands used as global directives.
3-Script is used by the Mathematica command Live that is available on platforms that support the GL library, such as Silicon Graphics computers. A 3-Script format file is written and this is passed to an external renderer to process. An alternative method you can use to pass a three-dimensional structure, or indeed any Mathematica expression into an external program, is to use the MathLink communications protocol.
A complete description of the 3-Script file format is contained in the Wolfram Research technical report, The 3-Script File Format, which can be found in the Mathematica Information Center, at http://library.wolfram.com; search the collection for `threescript'.
