rotate 2.20 ßeta *FREE*

Screenshot of version 2.00: (click on thumbnail)

rotate is a freeware program for PC's to view and rotate 3-D images in *.rot format, compatible with files written for Rotater (for the Mac). This format can contain single dots (which can be displayed at various sizes) and/or wireframes, in a number of colors. See below for some *.rot files.

I've started writing in the summer of '96 and since then over a dozen upgrades have been released. Many features were added thanks to feedback from users.

Brand new release of 16 March '99. What's new: more than two depth cueing shades, when the file does not require all color planes for its coloring.

The newsletter hasn't been sent for a long while, maybe next time when there's a new version.

The zip contains (DOS VGA program), as well as rotate.txt and whatsnew.txt (readme files) and copying.txt (GNU public licence). A number of sample *.rot files have been bundled.
Also contains notes for use in Windows, and the icon rotate.ico which you can assign to the program, as well as rotfile.ico which Windows 95/98 users can assign to the *.rot file type.
Also included a Windows 95/98 reg file to merge into your registry, with instructions. This automates much of the installation under Windows 95/98.
