1 \section{Creating your own object}
2 It is possible to create your own object in a separate file and
3 import it into the list of objects recognized by
4 \texttt{pst-solides3d}. Create a text file with the extension of \texttt{.pro}
5 (myObj.pro) and enter the PostScript commands to define your
6 \texttt{pst-solides3d} object.
8 Reference your \texttt{.pro} file in the preamble with
12 Following this line, add this new object to the list of objects recognized by \texttt{pst-solides3d}
15 \addtosolideslistobject{myObj}
18 For some examples of this technique, see the following web pages:

25 \section{Creating a \texttt{.u3d} file}
27 You can manipulate 3D objects created with \texttt{pst-solides3d};
28 the following three steps are necessary:
30 \item Save your designed 3D object in the \texttt{.off} or
31 \texttt{.obj} format---see the chapter ``\textit{Usage of external files}''.
33 \item Then use, for example, \textit{Meshlab}---an open source software---(\url{http://meshlab.sourceforge.net/}) to convert these files
34 into the \texttt{.u3d} format.
36 \item The {\LaTeX} package \texttt{movie15} of Alexander \textsc{Grahn} embeds
37 files in the \texttt{.u3d} format into a PDF document, the document can then be viewed
38 using $\text{Adobe}^{\text{\tiny\circledR}}$ $\text{Reader}^{\text{\tiny\circledR}}$ 7 or later.
