Rotater

A MacOS Program for rotating user specified 3D points and lines in real time with stereo viewing options.

Input is any text file with lines of 3D cordinates and a code specifying the color and action.

Versions are available for all Mac platforms dating back to Mac OS 9 on 68K.

Coming Soon

A completely rewritten version in SwiftUI using metal (pretty and fast)

For the adventurous

Rotater6.0a5.zip (Alpha build - MacOS 11 and above - tested on M1, should work on Intel)

Extended Versions

I have done some custom versions of Rotater for people and for
fun that others may have a use for. These versions are incomplete
to various degrees and are not supported. They are all Mac OS 9 programs.

Odd Versions (PPC):

Animated multiframe images that can be Rotated (279k)
4 dimensional model projection and rotation (147k)
Plots in 16 bit (thousands) of colors (170k)

Utilities

If you are looking for a quick and dirty DXF to Rotater Converter (19k) look no further (Mac OS 9 application).

Other Conversion and Generation Utilities sent in by people are available here too.

DOS/Windows Version

Marijke van Gans made a DOS version of Rotater some time ago. Details could be found at: http://www.silicon-alley.com/cat/rotate.html but it appears to have disappeared. This is what the site looked like.

There seems to be a copy at: https://people.eecs.berkeley.edu/~ddgarcia/research/graphics/Rotater/

Here is a local copy of the rotate.zip file from there.
