Line3d.exe by Peter Bone.

Here is a nice program where you can
create and rotate 3D stick figures.

(I emailed the software author since this link
wasn't working and he wrote to us below!!)

Here's one of my *.rot files that you can open and spin around.
It's okay to have blank lines in the *.rot file
as I have to separate the four leaves stemming in
tetrahedral fashion.

The four zero's are the end of the *.rot file.
The sevens make it draw in white or gray.
Maybe other colors can be used?
Zero's at the end of a line make that line invisible.

Ah, I really do enjoy playing around with these sort of programs, still the best one of these I've ever seen and used has to be megonphysics demo's they are so fun! the physics is so great. Ah I wish I could find it, it doesn't seem to exist on the web anywhere! if I do find it I will give you a link.

Re: Line3d.exe by Peter Bone.

Here's a nice 4-D binary logic figure I made up
with one missing point that belongs in the
4th dimension, so it is not shown.
The missing point is like the center point, but
somewhere behind in an unknown place to us.
So this 3-D figure has only 15 points, not 16.
Also note the four pretty colors, they mix a
bit on the overlapping lines in the file.
Name this data below anything.Rot and open
it in lines3d.exe and check the free-spin box
at bottom left, and spin it with your mouse!!!
Awesome!!

Re: Line3d.exe by Peter Bone.

Hello.

Creator of Lines3D here. I'm glad you like lines 3D.

My geocities site regularly breaks due to limited bandwidth but only for an hour. It comes back up after that. Lines3D is actually hosted elsewhere - only the html page is hosted on geocities. The URL of the file is http://atlas.walagata.com/w/peterbone/Lines3D.zip . This URL should be active all the time even if my geocities site is down.

You can have any colour lines you like by specifying the RGB value of the colour as well as the 7 pre-defined colours. Read the readme.txt file for further instructions.

Go here for a gallery of complex *.rot files
http://casr.adelaide.edu.au/rotater-gallery

Hope that helps.

Peter Bone
