    This article describes how to use level sets to represent and compute deformable surfaces. A deformable surface is a sequence of surface models obtained by taking an initial model and incrementally modifying its shape. Typically, we can parameterize the deformation over time, and thus we can imagine that a surface moves or flows under the influence of a vector field. The surface flow, v, can be de...

    With the flood of data across all aspects of the pharmaceutical industry, information visualization is emerging as a critical component of discovery, development, and business. But it's a new class of visualizations that is having the greatest impact. Higher-level summaries that can provide a framework for understanding the immense volumes of data and that reveal unexpected relationships have come... View full abstract»

    In this article, the author describe issues of scale that arise at all stages of the visual exploration process and give examples of some solutions to these problems that his group at Worcester Polytechnic Institute have experimented with over the past several years. While the work has predominantly focused on nonspatial multivariate data analysis, he feels that many of the concepts and approaches... View full abstract»

    Professional analysts deal with a high volume of information and must constantly work to separate out the valuable data. However, analysts have difficulty determining what data is useful without reading or skimming almost all returned documents from a search. This presents them with a difficult tradeoff. Searching information broadly returns hundreds or thousands of documents. We present lessons l... View full abstract»

    The task of sifting through large amounts of data to find useful information spawned the field of data mining. Most data mining approaches are based on machine-learning techniques, numerical analysis, or statistical modeling. They use human interaction and visualization only minimally. Such automatic methods can miss some important features of the data. Incorporating human perception into the data... View full abstract»

    Visual data-mining techniques have proven valuable in exploratory data analysis, and they have strong potential in the exploration of large databases. Detecting interesting local patterns in large data sets is a key research challenge. Particularly challenging today is finding and deploying efficient and scalable visualization strategies for exploring large geospatial data sets. One way is to shar... View full abstract»

    This article describes our design and evaluation of a multisensory human perceptual tool for the real-world task domain of stock market trading. The tool is complementary in that it displays different information to different senses - our design incorporates both a 3D visual and a 2D sound display. The results of evaluating the tool in a formal experiment are complex. The data mined in this case s... View full abstract»

    We investigate how to represent the resulting multivariate information and multidimensional uncertainty by developing and applying candidate visual techniques. Although good techniques exist for visualizing many data types, less progress has been made on how to display uncertainty and multivariate information - this is especially true as the dimensionality rises. At this time, our primary focus is... View full abstract»

    Information sharing and social interaction are the Web's main features that have enabled online communities to abound and flourish. However, the Web is lacking cues and browsing mechanisms for the online social spaces. The challenge of creating social browsing tools to access such social information and patterns is of interest as a visual analytic problem for two reasons. Browsers that combine soc...

    Many painters today are going digital; because of the convenience and ease of experimentation that painting software gives. Our goal is to effectively simulate the process of brush painting - particularly the dynamics of a brush tuft - so that artists can use a virtual brush to paint with spirit - that is, in a lively, dynamic, brisk way. We've designed an efficient deformable brush model with spr... View full abstract»

    In this paper we give the solution for the following geometric problem. Given four arbitrarily placed lines in space, K, L, M, and N, find a fifth line V that intersects all four. And if there is more than one, find all of them. The author aims at an analytic solution and have developed some notation and basic tools for manipulating lines in projective 3-space; and used these tools on lines in spa... View full abstract»
