Protovis Protovis composes custom views of data with simple marks such as bars and dots. Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction. Protovis is free and open-source, provided under the BSD License. Protovis is no longer under active development.The final release of Protovis was v3.3.1 (4.7 MB). This project was led by Mike Bostock and Jeff Heer of the Stanford Visualization Group, with significant help from Vadim Ogievetsky. Updates June 28, 2011 - Protovis is no longer under active development. September 17, 2010 - Release 3.3 is available on GitHub. May 28, 2010 - ZOMG! October 1, 2009 - Release 3.1 is available, including minor bug fixes. September 19, 2009 - Release 3.0 is available, including major performance improvments, bug fixes, and handy utilities such as scales and layouts. Getting Started How does Protovis work?
PWGL - PWGL PWGL is a visual language based on similar concepts than PatchWork. PWGL has been designed from scratch and it contains several improvements when compared with PW. For example, the graphics part of the system has been realized in OpenGL. OpenGL offers several advantages such as multi-platform support, hardware acceleration, floating-point graphics and sophisticated 2D and 3D-graphics. PWGL is a multi-window system. PWGL has a library of predefined input-boxes which typically handle numbers, lists and objects. Figure 1 gives a typical PWGL patch-window containing a 2D-editor and some basic boxes. In Figure 2 the patch calculates harmonic and inharmonic overtone series. Figure 3 shows an example of a PWGL user-library by Magnus Lindberg.
A Tour Through the Visualization Zoo Jeffrey Heer, Michael Bostock, and Vadim Ogievetsky Stanford University Introduction Thanks to advances in sensing, networking, and data management, our society is producing digital information at an astonishing rate. According to one estimate, in 2010 alone we will generate 1,200 exabytes — 60 million times the Library of Congress. Within this deluge of data lies a wealth of valuable information on how we conduct our businesses, governments, and personal lives. To put the information to good use, we must find ways to meaningfully explore, relate, and communicate the data. The goal of visualization is to aid our understanding of data by leveraging the human visual system's highly-tuned ability to see patterns, spot trends, and identify outliers. Creating a visualization requires a number of nuanced judgments. In this article, we provide a brief tour through the "visualization zoo," showcasing techniques for visualizing and interacting with diverse data sets. Time-Series Data Index Charts
Syntopia This is the last post in my introduction to distance estimated 3D fractals (see Part one for an overview). Originally, I intended this to be much shorter and more focused, but different topics kept sneaking up on me. This final post discusses hybrid systems, and a few things that didn’t fit naturally in the previous posts. It also contains a small collection of links to relevant resources. Hybrids All the fractal systems mentioned in the previous parts apply the same transformation to each point for a number of iterations. Spudsville It is difficult to trace the origin of many of these hybrids, since they are often cloned and modified. It is based on the following recipe: 5 x { Mandelbox, i.e. Pseudo Kleinian This is another popular base form, based on parameters from Theli-at’s Kleinian Drops. 12 x { Scale -1 Mandelbox } 1 x {BoxFold, Mandelbulb power-2 Squaring } 400 x { Scale 2 Mandelbox } and Pseudo-Kleinian Blue: There really is no end to the possibilities. 7 x { Mandelbox, i.e. Resources
Kaleidoscopic (escape time) IFS Hello,Here are some renderings of a class of fractals which I call "Kaleidoscopic IFS". There is a big variations of shapes one can get with this method.I began with this algorithm to get DE for symmetric Sierpinski tetrahedron: Then I added a rotation before the fold or before the stretch or both. //scale=2//bailout=1000sierpinski3(x,y,z){ r=x*x+y*y+z*z; for(i=0;i<10 && r<bailout;i++){ rotate1(x,y,z); if(x+y<0){x1=-y;y=-x;x=x1;} if(x+z<0){x1=-z;z=-x;x=x1;} if(y+z<0){y1=-z;z=-y;y=y1;} rotate2(x,y,z); x=scale*x-(scale-1); y=scale*y-(scale-1); z=scale*z-(scale-1); r=x*x+y*y+z*z; } return (sqrt(r)-2)*scale^(-i);//the estimated distance} Then I allowed the center of stretching to be modified. x=scale*x-CX*(scale-1); y=scale*y-CY*(scale-1); z=scale*z-CZ*(scale-1); r=x*x+y*y+z*z; } return (sqrt(r)-2)*scale^(-i);//the estimated distance} The set of folding operation may be different. if(x+y<0){x1=-y;y=-x;x=x1;} if(x+z<0){x1=-z;z=-x;x=x1;} if(y+z<0){y1=-z;z=-y;y=y1;} - cubic symmetry planes: Ah!
Web Structure Visualisation Any web, including more especially the world wide web as a whole, is composed of pages (which we'll call nodes) and links between them (which we'll call arcs). This means that, from a mathematical standpoint, we can consider the structure of any website as a graph. Consequently, in order to represent the structure of a website we simply need to draw a graph. Simple? Bu we aren't interested here in the different ways of drawing graphs in general but in how their visualisation can help us to understand the structure of a website in order to then take appropriate decisions and implement them. Consequently, we'll see some of the visualisations that have appeared with this goal. Many of them fall into the category of focus+context representations since they allow the user to see the whole content of the web, while establishing an attention focus (for example in a certain page) which can be accessed in greater detail. Here you find some of the most promising representations: ConeTrees: Conclusion
Visualisation of Live Code « Alex McLean I wrote a paper with Dave Griffiths and Nick Collins on the visualisation of live code, exploring ideas around live coding interfaces, accepted for the EVA London 2010 conference in July. A HTML version is below, or see the PDF Preprint. Alex McLean (Goldsmiths), Dave Griffiths (FoAM), Nick Collins (University of Sussex) and Geraint Wiggins (Goldsmiths) Abstract In this paper we outline the issues surrounding live coding which is projected for an audience, and in this context, approaches to code visualisation. 1. Live coding, the improvisation of video and/or music using computer language, has developed into an active field of research and arts practice over the last decade (Wang and Cook; 2004; Ward et al.; 2004; Collins et al.; 2003). A frequent criticism of computer music is the lack of performance, where an artist hides behind their laptop screen, and the audience is unable to see any activity that might ground their experience of the music (Cascone; 2003). 2. 2.1. 3. 3.1. 3.2. 4.

…/… Archive for …/… Patrik Schumacher on Art &/vs Architecture Extract from Patrik Schumacher (Zaha Hadid Architects) recent argumentation published on Face Book that followed the release of Architecture Biennale program: Once more on the distinction and relation between art and architecture: Historically painting, sculpture and architecture were a continuous practice engaged in by the same protagonists (Michelangelo, Rafael, Bernini etc.) for a unified purpose. The framing communications that architects provide are attributed to the host institutions that invite participants into their spaces and not to the architects. (Francois, I hope you don’t take offence at my reflections on you as a “category mistake” … your work, disciplinary position and persona are theoretically very intriguing, the exception that confirms the rule, the paradigm case or exemplar that allows the demarcation problem to be made concrete and could be discussed with a degree of specificy … but that would be another post.)
