The KnotPlot Site

Welcome to the KnotPlot Site! Here you will find a collection of knots and links, viewed from a (mostly) mathematical perspective. Nearly all of the images here were created with KnotPlot, an elaborate program to visualize and manipulate mathematical knots in three and four dimensions. Download KnotPlot for Windows, MacOSX and Linux Check out the mathematical knots (M) page as well to see more knot pictures. Or try some of the following examples to see some knots in a different light.

amMap: Interactive flash maps Features Main features Highly customizable – every aspect of the map can be styled using built-in configuration options or CSS.Create multi-level drill-downs.Create map charts (heatmaps or otherwise known as choropleth maps).Use any images in any format as map markers.Support for real-life latitude and longitude coordinates.Apply built-in or custom textures.Display multi-segment lines and routes.Customize initial and user-controllable zoom options.Control the map via JavaScript API (change data and configuration options, simulate user interactions, attach custom funcitonality to various events, etc.) Hundreds of maps JavaScript Maps comes with hundreds of hand-crafted maps in two detail levels – low-resolution (to conserve bandwidth) and high-resolution (for extra detail).

Celtic Knots, Truchet tiles, Combinatorial Patterns This is made by using a “Celtic Knot font” (from clanbadge.com). Basically, this method is just a combination of square tiles. Each tile has a pattern. When 2 tiles are placed together, the pattern on them connect at the edges. 50 Great Examples of Data Visualization Wrapping your brain around data online can be challenging, especially when dealing with huge volumes of information. And trying to find related content can also be difficult, depending on what data you’re looking for. But data visualizations can make all of that much easier, allowing you to see the concepts that you’re learning about in a more interesting, and often more useful manner.

Reed's Celtic Computer "Art" Site I'm Reed Mihaloew (known in the Society for Creative Anachronism (SCA) as Rolin Thurmundsson, and available through e-mail at "[last name] [at] mitre [dot] org"). I've been interested in Celtic-style art since the late 70's, having been introduced to it through the SCA. My original work was all done by hand, but I started to experiment with computer drawn work in the early 80's; originally on a Mac. My current computer environment is described in Tools and Techniques below. I originally experimented with "drawing" type packages (e.g., MacDraw) trying to achieve the best control over the lines and bands in the knotwork.

Animating Water Using Flow Maps Last week I attended SIGGRAPH 2010, and among the many good presentations, Valve game a talk on the simple water shader they implemented for Left For Dead 2 and Portal 2. So on the plane ride back from LA, I whipped up this little sample from what I could remember of the talk. Edit: You can find the talk here: The standard technique for animated water is scrolling normal maps, as I’ve previously written about. The problem with this is that it looks unnatural as water does not uniformly move in one direction.

MoMA Adds Video Games to Its Collection Brendan Hoffman for The New York TimesPac-Man was included in an exhibition at the Smithsonian American Art Museum earlier this year. If you have been disparaging video games – or, perhaps, trying to wean yourself from an addiction to them – it’s time to think again. Video games are now high culture, with the imprimatur of the Museum of Modern Art, which announced on Thursday that it has acquired the first 14 titles in a planned collection of about 40 games. These constitute a new category among the museum’s collections, and will be on display in the Philip Johnson Galleries starting in March. (An exhibition devoted to video games will open in December at the Museum of the Moving Image, and another exhibition, at the Smithsonian American Art Museum, closed in September.)
