Useful free software downloads

Click on the buttons on the left to download and begin to install the following software.

	You should make sure you have the most up-to-date version of your favorite Web browser. I have no scruples against using software from Microsoft; I use Internet Explorer and can recommend it to you enthusiastically, but of course...
	...most of you probably use Netscape Navigator, and that will work just as well. I would still encourage you to use the latest version.
	No matter which browser you use, you'll want to use it on the many PDF files in this site, so you will need to download and install Adobe Acrobat Reader, if you haven't already done so, or if you don't already have the full version of Adobe Acrobat installed. (The latter is highly recommended to those who can afford it.)
	We won't be using PostScript files very often (if at all), but if you have any use for a PostScript viewer, or a mechanism for spooling such files to your PC or Macintosh printer, you'd probably like Ghostview.
	We will do all of our computer raytracing for this class with Raytrace 5.0, written by Profs. Jim Houck and Terry Herter of Cornell University. Click at left to download a self-extracting collection of files, including the executable version and some sample optical prescriptions.
