the light in modern concept has accompanied by theater as one of the formative elements of showing art from the first days of theater emergence and todays various functions have been defined for that and it has been and is being used for different purpose. on the other hand, the light is always with shadow on the scene and lack of light causes to darkness on the scene. so, the light, shadow, an...

The question of how local image features on the retina are integrated into perceived global shapes is central to our understanding of human visual perception. Psychophysical investigations have suggested that the emergence of a coherent visual percept, or a "good-Gestalt", is mediated by the perceptual organization of local features based on their similarity. However, the neural mechanisms that...

in the modern era and through abstraction, art turns to a path in which the beginning and end of an artwork get closer together than in any other era in an attempt to make the minimum space between the subject and the object, or the work and viewer so that the work is created while receiving the minimum influence from the external world and maximum closeness to the very essence of abstraction a...

This paper presents a perceptually motivated formal framework for effective visualization of relational data. In this framework, the intended structure of data and the perceptual structure of visualizations are formally and uniformly defined in terms of relations that are induced on data and visual elements by data and visual attributes, respectively. Visual attributes are analyzed and classifi...

This paper discusses group decision making from a visual-interactive perspective. The novelty of our approach is that its major focus is on developing a collection of visualinteractive elements for group decision-making. Our research departs from a collection of representative meeting scenarios to identify common decision-making elements and behavior similarities; and to elaborate a collection ...

We present SciVL, the Scientific Visualization Modeling Language, a new way to describe scientific visualizations of multivariate, twodimensional datasets. Our goal was to create a language with which a user could rapidly prototype complex and precise data-driven visualizations as well as facilitate their modification during the iterative design process. Our language can combine three types of ...
