Hypnagogic Software is pleased to announce that KnotPlot 1.0, the World's most elaborate knotting software is now available for the low price of only $35.00 (Canadian dollars). Buy now and enjoy the following advantages:
If you wish to evaluate the software before purchasing it, just download it using one of the links below. The evaluation version of KnotPlot is completely free, but many features have been disabled. You can always upgrade your KnotPlot version by simply returning to this web page and purchasing a key later. The free evaluation version becomes the full version when the key is installed.
KnotPlot 1.0 is available now for all Windows platforms, MacOSX (both PowerPC and Intel), Linux, and IRIX. Click on the button below to purchase KnotPlot using PayPal (you can use a credit card). All transactions are secure.
You don't need a PayPal account, most credit cards are accepted. After you purchase KnotPlot, you will receive an email from firstname.lastname@example.org with your key. Just install the software and your key, and you will be set to start plotting knots!

Installing KnotPlot is easy, just click on one of the links below to install the software. When you first install KnotPlot, it will be the free evaluation version (which has features disabled). If you wish to have the full version of KnotPlot, purchase a key using the Buy now button above. Fairly soon after you make the purchase, you will receive an email from email@example.com with a key and instructions on how to install it. After the key is installed, you will be up and running KnotPlot with all features enabled.
Here are the downloads for KnotPlot. KnotPlot needs two components, the executable, which is the program itself, and the KnotPlot distribution, which is the approximately 5,959 files that KnotPlot just can't live without. If you're installing on a Windows or MacOSX machine, you only need one file, which contains both the executuable and the distibution. The MacOSX distribution is provided in two versions, one for the older PowerPC Macs, and one for the new Intel-based Macs. The Intel Macs will actually run both versions, but performance is much better if you use the version compiled for Intel. On Linux platforms, you need to download the executable and the distribution separately. NOTE: Some browsers may strip the file name extensions (such as .gz) without actually gunzipping the file. If you're downloading one of the files below, make sure that your browser saves it with the correct file name.
One thing to make sure of is that you have the proper OpenGL driver installed! On Macs, this is always the case, but many Windows machines with good graphics cards sometimes do not have the OpenGL driver installed, and may be using software rendering (i.e., no hardware acceleration). A similar situation exists for Linux platforms.

Information on installation is available for the following platforms:
To access all the features of KnotPlot, you will need to install a key. This key will be emailed to the address you supplied when you purchased KnotPlot using PayPal. This will happen fairly soon after purchase, usually within a few hours. Instructions on what to do with the key will also be provided.
The MacOSX version has a few oddities that deserve mentioning. In general, you should ignore all the standard Mac menus, use the KnotPlot menus instead (right-click or control-click on the KnotPlot Control Panel).
Secondly, I recommend reading the Read Me.pdf file that comes in the distribution. It has a few suggestions, for example placing the KnotPlot application in its own folder. For Snow Leopard (MacOSX 10.6) or Lion (MacOSX 10.7), there are also some small utilities that are useful when working on different projects. These utilities help in getting KnotPlot to save files to a specific folder/directory.
A hopelessly out of date (and sometimes wrong) version of the manual is available. The good news is that if you want to create light weight EPS (Encapsulated PostScript) pictures with KnotPlot, there is an up to date (but small) PSexamples manual as well as an extensive web page of PostScript and PDF examples, together with the KnotPlot commands used to create them.
The PDF version (updated 15 October 2002) is much more up to date than the HTML version, although it is still incomplete. I recommend you download the PDF version instead of consulting the HTML version.
A quick startup guide to using KnotPlot is also available (handout.pdf), as are five small tutorials (ex1.pdf, ex2.pdf, ex3.pdf, ex4.pdf, ex5.pdf).
This section is of interest to those using KnotPlot to study DNA topology. Included in the KnotPlot distribution is the Topological Interactive Construction Engine, or TopoICE, which implements Isabel Darcy's algorithms for solving tangle equations. TopoICE comes in two flavours TopoICE-X and TopoICE-R. The following support files for TopoICE are provided.
