EVALITA is an initiative of the Italian Association for Computational Linguistics (AILC, http://www.ai-lc.it) and it is endorsed by the Italian Association for Artificial Intelligence (AIxIA, http://www.aixia.it) and the Italian Association for Speech Sciences (AISV, http://www.aisv.it)

Non-photorealistic computer graphics: modeling, rendering, and animation

Even as developments in photorealistic computer graphics continue to affect our work and leisure activities, practitioners and researchers are devoting more and more attention to non-photorealistic (NPR) techniques for generating images that appear to have been created by hand. These efforts benefit every field in which illustrationsthanks to their ability to clarify, emphasize, and convey very precise meaningsoffer advantages over photographs. These fields include medicine, architecture, entertainment, education, geography, publishing, and visualization. Non-Photorealistic Computer Graphics is the first and only resource to examine non-photorealistic efforts in depth, providing detailed accounts of the major algorithms, as well as the background information and implementation advice readers need to make headway with these increasingly important techniques. Already, an estimated 10% of computer graphics users require some form of non-photorealism. Strothotte and Schlechtweg's important new book is designed and destined to be the standard NPR reference for this large, diverse, and growing group of professionals. *Hard-to-find information needed by a wide range and growing number of computer graphics programmers and applications users. *Traces NPR principles and techniques back to their origins in human vision and perception. *Focuses on areas that stand to benefit most from advances in NPR, including medical and architectural illustration, cartography, and data visualization. *Presents algorithms for two and three-dimensional effects, using pseudo-code where needed to clarify complex steps. *Helps readers attain pen-and-ink, pencil-sketch, and painterly effects, in addition to other styles. *Explores specific challenges for NPRincluding "wrong" marks, deformation, natural media, artistic technique, lighting, and dimensionality. *Includes a series of programming projects in which readers can apply the book's concepts and algorithms.Includes bibliographical references (pages 409-427) and index.Pixel manipulation of images -- Lines, curves, and strokes -- Simulating natural media and artistic techniques -- Stroke-based illustrations -- Working with 2.5D data structures -- Geometric models and their exploitation in NPR -- Lighting models for NPR -- Distorting non-realistic renditions -- Applications for NPR -- A conceptual framework for NPR.Print version record.Even as developments in photorealistic computer graphics continue to affect our work and leisure activities, practitioners and researchers are devoting more and more attention to non-photorealistic (NPR) techniques for generating images that appear to have been created by hand.

Interactively Exploring Bibliographical Data for Literature Analysis

This paper introduces techniques for interactive navigation within large sets of bibliographic data. The main conceptual idea is to use various relations between the entries to navigate within the information space. A visualization that supports both the display of the data itself and the relations is introduced. Interaction techniques offer possibilities to follow relations and, thus, create new views onto the data. The proposed visualization and interaction techniques improve literature analysis tasks as occur when writing a scientific document or when reviewing and exploring a scientific topic based on literature

Connecting Time-Oriented Data and Information to a Coherent Interactive Visualization

In modern intensive care units (ICUs), the medical staff has to monitor a huge amount of high-dimensional and timeoriented data, which needs to be visualized user- and taskspecifically to ease diagnosis and treatment planning. Available visual representations, like diagrams or charts neglect the implicit information as well as a-priory or associated knowledge about the data and its meaning (for example, 38.5°C (101.3°F) is moderate fever and 41°C (105.8°F) is critical fever). Another challenge is to provide appropriate interaction techniques to explore and navigate the data and its temporal dimensions. In this context one major challenge is to connect time-oriented data and information to a coherent interactive visualization. In this paper we present different interactive visualization techniques which enable the users to reveal the data at several levels of detail and abstraction, ranging from a broad overview to the fine structure. We will also introduce a time visualization and navigation technique that connects overview+detail, pan+zoom, and focus+context features to one powerful time-browser

Rendering Line-Drawings with Limited Resources

Pictures play an important role in the communication process. Communicative goals can be expressed for instance with the specific use of different levels of abstraction in pictures. Especially in textbooks and scientific publications, images are used where the level of detail of different objects is deliberately changed to express the importance of an object in the picture. In this paper we introduce the concept of "drawing resources " for rendered line-drawings. This concept defines measures for controlling the level of detail of single objects in a drawing. We present a system which is based on a line-renderer and which enables a user to interact with the drawing thus created. The concept of drawing resources yields a new basis for formulating the user's ideas of the appearance of the final image. Keywords: non-photorealistic rendering, linedrawings, level of detail, abstraction. 1 Introduction The emphasis of rendering techniques has traditionally been on producing a detailed, c..

Magic Pages -- Providing Added Value to Electronic Documents

Most electronic documents have a predefined structure, and a visualization of a document is adjusted to this structure. In many cases, however, it is desirable to have different visual representations of the document. This becomes especially important if there is additional information available, for instance, annotations. This paper introduces Magic Pages, a user interface technique that supports different views onto an electronic document. Support in this case means to provide an intuitive way of handling the visualization of textual content as well as additional information. Magic Pages are designed based on the user's experience with the handling of paper documents and treat different views as transparent pages set atop the original text

RenderBots -- Multi Agent Systems for Direct Image Generation

The term stroke-based rendering collectively describes techniques where images are generated from elements that are usually larger than a pixel. These techniques lend themselves well for rendering artistic styles such as stippling and hatching. This paper presents a novel approach for stroke-based rendering that exploits multi agent systems. RenderBots are individual agents each of which in general represents one stroke. They form a multi agent system and undergo a simulation to distribute themselves in the environment. The environment consists of a source image and possibly additional G-buffers. The final image is created when the simulation is finished by having each RenderBot execute its painting function. RenderBot classes differ in their physical behavior as well as their way of painting so that different styles can be created in a very flexible way
