There are several interactive drawing programs at the Supercomputing Institute. On the SGI workstations, Showcase is one of the most flexible and easiest to use. For drawings that will be incorporated into a TeX or LaTeX document, use xfig so that the fonts of the drawing match the fonts of document.
Showcase is a powerful drawing and mixed media tool. With showcase, you can create on-screen slide shows with images, sound, videos and 3D models. Showcase can be used to annotate encapsulated PostScript and SGI's rgb images. In addition to sound, video and 3D capabilities, Showcase has all the features of most drawing programs. Showcase can output PostScript files and files in its own format for later manipulation. A man page is available ( man showcase) and a user manual is online through SGI's Insight library.

Tgif is a drawing program. One of the main features of tgif: it is one of the few programs that can annotate an encapsulated postscript image. In addition to annotating an encapsulated postscript file, tgif can be used to scale, rotate or flip the image. It is probably the best tool at the Supercomputing Institute for annotating PostScript vector graphics (Here a line is stored as two endpoints, rather than all the pixels that make up a line. Thus rotation and scaling are simple and precise operations.) As with most drawing programs, tgif can draw lines, rectangles, arc, polygons, splines, and text. Tgif can output the drawing in one of 4 different formats: PostScript, Encapsulated Postscript, X11 bitmaps and X11 pixmaps. Tgif can also save the objects in its own format for later manipulation. A man page is available(man tgif).
Note: Before using tgif, add the following line to the file ".Xdefaults" in your home directory.
Without this line, tgif will scale the encapsulated postscript images that you import. Tgif uses 128 pixels per inch, postscript uses 72 pixels per inch. Therefore we must scale images by 128/72, which is 1.7778 to preserve the size.

Xfig is a menu-driven tool that allows the user to draw and manipulate objects interactively in an X window. The pictures that are drawn with xfig may be converted to one of several formats, including encapsulated PostScript which allows their inclusion in LaTeX documents. With xfig, you can also annotate images, including encapsulated postscript, X11 bit and pixmap, GIF and JPEG images. When used in conjunction with LaTeX, it is possible to send the pictures directly to postscript, and the text to LaTeX so that fonts in the image will be the same as in the LaTeX document. Documentation can be obtained on-line by typing man xfig.
