Computer graphics visions and challenges: a European perspective
IEEE Computer Graphics and Applications, 2006I have briefly described important visions and challenges in computer graphics. They are a personal and therefore subjective selection. But most of these issues have to be addressed and solved--no matter if we call them visions or challenges or something else--if we want to make and further develop computer graphics into a key enabling technology for ...

Computer graphical treatments of perspective pictures
Computers & Graphics, 1988Abstract The treatment of perspective pictures with the help of computers requires thorough knowledge of geometry for describing the change between object and picture by mathematical formulas before programs for the different tasks (design, discussion, rectification and montages of pictures) can be made.

The evolution of graphic representations in a Vygotskijan perspective [PDF]
, 2003 In this paper we propose a constructivistic approach to the Cartesian plane. We look at it as a linguistic-graphic structure grounded in a cognitive function recognizable in the natural drawings of children. Then we hypothize for it a development process following the same path as in Vygotskijan model for natural vs. scientific language.

Background and perspectives of possibilistic graphical models
1997Graphical modelling is an important tool for the efficient representation and analysis of uncertain information in knowledge-based systems. While Bayesian networks and Markov networks from probabilistic graphical modelling are well-known for a couple of years, the field of possibilistic graphical modelling occurs as a new promising area of research ...

Computer graphics interface: A developer's perspective
Computer-Aided Design, 1987The Computer Graphics Interface (CGI) is introduced and analysed with respect to the current needs of device manufacturers, systems designers, and users. Discussion includes topics such as the progress of CGI development, the features of the CGI, and the CGI's fundamental goals. Emphasis is placed on how well the CGI relates to 'real world' application

Background to and Perspectives on Possibilistic Graphical Models
1998Graphical modelling is an important tool for the efficient representation and analysis of uncertain information in knowledge-based systems. While Bayesian networks and Markov networks from probabilistic graphical modelling have been well-known for about ten years, the field of possibilistic graphical modelling appears to be a new promising area of ...

Perspective-Correct Formation of Graphic Images
The article presents advancements in color reproduction techniques, enhancing the realism of graphic scenes. It introduces novel methods for accurate shading of three-dimensional objects, improves the Barenbrug perspective-correct texturing method, and proposes quadratic approximation for perspective-correct texturing, reducing computation time and ...Oleksandr Romanyuk, Oksana Romaniuk

Perspectives of Non-photorealistic Computer Graphics
2010Non-photorealistic computer graphics has created an intriguing new field espousing expression, abstraction and stylization in preference to traditional computer graphics concerns about photorealism. It has two complimentary goals: the communication of information using images and rendering images in interesting and novel visual styles which are free ...
