Opp: Student stipend to attend I3D 2012

An opp to attend the ACM I3D event on the event's dime.

I3D is the main event that focuses on graphics applicable to games. It's a nice small event that affords many chances to meet with attendees, unlike siggraph, which is far too large and crazy to make cold meetings easy.

ACM Symposium on Interactive 3D Graphics and Games (I3D) 2012
We are offering a student stipend to sponsor three students attending
I3D 2012. The program is open to students worldwide (at the
undergraduate or graduate level, or equivalent) who have not
previously published at I3D. Three stipends of 200 US dollars each
will be awarded to reimburse travel, hotel and meals. Since the
program objective is to encourage participation of students new to I3D
and perhaps new to 3D graphics, stipends will not be given to students
who are authors or co-authors of accepted papers or those who have
published at I3D earlier. Poster presenters may apply for a stipend.

To apply for the stipend, please send an application packet to
stipends@i3dsymposium.org by no later than Sunday December 18th,
11:59PM PST, 2011. The applications will be reviewed by committee and
the recipients of the stipends will be notified via email. Your
application packet should be a single PDF file (e.g., print using
PDFCreator) containing the following parts:

- Contact information: your name, mailing address, and an email
- Faculty contact: please include the name and email address of your
advisor or a professor who supports your application to the Student
Stipend Program.
- Resume: please include an up-to-date resume or CV.

If you have further questions regarding the I3D Student Stipend
Program, please send an email to stipends@i3dsymposium.org before the
deadline. Also, see the I3D website for more details about the
conference. I look forward to your application and to seeing you at
I3D 2012!

Find: Google's Graphing Calculator -- sweet, reverse polish now please

And a gadoodle in honor of the hp calc on top.

Google's Graphing Calculator

Now you no longer need to use Wolfram Alpha to plot Math graphs. Google shows an interactive graph when you search for a Math function or a list of functions separated by commas. "You can zoom in and out and pan across the plane to explore the function in more detail. This feature covers an extensive range of single variable functions including trigonometric, exponential, logarithmic and their compositions, and is available in modern browsers," explains Google.
For example, you can search for [sin(x)/x, 1/x^2] to see this beautiful SVG graph.

The Legacy of Steve Jobs -- great retrospective in acm mag

Number of good points here, including that jobs figured out a way to turn high design into a platform.

Spotted: An Optimal Control Approach for Texture Metamorphosis

Texture perception is still poorly understood. We've given thought to this problem. 

An Optimal Control Approach for Texture Metamorphosis


In this paper, we introduce a new texture metamorphosis approach for interpolating texture samples from a source texture into a target texture. We use a new energy optimization scheme derived from optimal control principles which exploits the structure of the metamorphosis optimality conditions. Our approach considers the change in pixel position and pixel appearance in a single framework. In contrast to previous techniques that compute a global warping based on feature masks of textures, our approach allows to transform one texture into another by considering both intensity values and structural features of textures simultaneously. We demonstrate the usefulness of our approach for different textures, such as stochastic, semi-structural and regular textures, with different levels of complexities. Our method produces visually appealing transformation sequences with no user interaction.

Spotted: Building look & feel concept models from color combinations

Interesting topic, wonder if they got any real traction? 

Building look & feel concept models from color combinations

In this paper, we tackle the problem of associating combinations of colors to abstract concepts (e.g. capricious, classic, cool, delicate, etc.). Since such concepts are difficult to represent using single colors, we consider combinations of colors or color palettes. We leverage two novel databases for color palettes, and learn categorization models using both low and high level descriptors.
It is shown that the Bag of Colors and Fisher Vectors are the most rewarding descriptors for palettes categorization and retrieval.

Spotted: Empirical Studies in Information Visualization: Seven Scenarios

Sheelagh and catherine are leaders in viz evaluation. Should be interesting. 

PrePrint: Empirical Studies in Information Visualization: Seven Scenarios

We take a new, scenario based look at evaluation in information visualization. Our seven scenarios, evaluating visual data analysis and reasoning, evaluating user performance, evaluating user experience, evaluating environments and work practices, evaluating communication through visualization, evaluating visualization algorithms, and evaluating collaborative data analysis were derived through an extensive literature review of over 800 visualization publications. These scenarios distinguish different study goals and types of research questions and are illustrated through example studies. Through this broad survey and the distillation of these scenarios we make two contributions. One, we encapsulate the current practices in the information visualization research community and, two, we provide a different approach to reaching decisions about what might be the most effective evaluation of a given information visualization. Scenarios can be used to choose appropriate research questions and goals and the provided examples can be consulted for guidance on how to design one's own study.

Spotted: Graph Drawing Aesthetics—Created by Users, Not Algorithms

Users don't like edge crossings, and do like node alignment. 

Graph Drawing Aesthetics—Created by Users, Not Algorithms

Prior empirical work on layout aesthetics for graph drawing algorithms has concentrated on the interpretation of existing graph drawings. We report on experiments which focus on the creation and layout of graph drawings: participants were asked to draw graphs based on adjacency lists, and to lay them out "nicely.” Two interaction methods were used for creating the drawings: a sketch interface which allows for easy, natural hand movements, and a formal point-and-click interface similar to a typical graph editing system. We find, in common with many other studies, that removing edge crossings is the most significant aesthetic, but also discover that aligning nodes and edges to an underlying grid is important. We observe that the aesthetics favored by participants during creation of a graph drawing are often not evident in the final product and that the participants did not make a clear distinction between the processes of creation and layout. Our results suggest that graph drawing systems should integrate automatic layout with the user's manual editing process, and provide facilities to support grid-based graph creation.

Find: Interview with SIGGRAPH ASIA 2011 Speaker & Microsoft Researcher Bill Buxton

Glad bill also thinks displays are a big part of the future of graphics. He's always been a leader in bringing the human element to the field. 

Interview with SIGGRAPH ASIA 2011 Speaker & Microsoft Researcher Bill Buxton

Bill Buxton, a principal researcher for Microsoft Research, will be making a presentation during SIGGRAPH Asia. He recently got a chance to discuss his work.
