From: iccg93@saathi.ncst.ernet.in Subject: CONF: Intl Conf on Computer Graphics 93, Bombay, Feb 1993 Date: 31 Dec 92 18:17:51 GMT Message-ID: <11587@sun13.scri.fsu.edu> Crossposted from comp.graphics.research ICCG 93 ------- INTERNATIONAL CONFERENCE ON COMPUTER GRAPHICS: ---------------------------------------------- Interaction, Design, Modeling and Visualisation ------------------------------------------------ BOMBAY, INDIA February 22 - 26, 1993 Organised by International Federation for Information Processing (TC5 -- WG 5.2 and WG 5.10) and Computer Society of India ------------------------------------------------------------------------------- Welcome to ICCG93 ------------------------------------------------------------------------------- Computer Graphics is continuously evolving to new levels of creative accomplishments and technological sophistications with new concepts, new techniques and an ever increasing spectrum of applications. Modern computing is largely interactively driven and computational results are more often communicated visually rather than just in print. The main goal of ICCG93 is to provide an international forum for the presentation and discussion of recent developments in the fields of Graphics and CAD including case studies in systems and applications, and state of the art surveys. The ICCG93 technical programme is addressing all the current "hot" topics in the field under the themes of graphical interaction, design, modelling, rendering and visualisation. This includes five pre-conference tutorials, keynote addresses and a number of invited talks all being given by professionals of international eminence coming from different countries. ICCG93 is providing a NOT TO BE MISSED UNIQUE OPPORTUNITY to all professionals interested in Graphics and its various applications. The conference includes over thirty presentations reporting the latest research and developments being carried out worldwide. These will be presented at the conference by leading experts from 14 different countries whose papers have been carefully selected by the international programme committee of ICCG93. The conference also provides an opportunity for the computer graphics academia and the industry to come together through the ICCG93 exhibition and industry seminars. Bombay being the hub of industrial activity in India provides an excellent setting for this interaction. We are sure you will agree with us that in India an opportunity such as this with a technical programme of this high quality does not come our way very often. The success of ICCG93 depends very much on your joining us and actively participating in the proceedings of the conference. We look forward to seeing you and your colleagues in Bombay in February. Mudur S P Narayanan J P Chairman, Programme Committee Chairman, Organising Committee ------------------------------------------------------------------------------- Pre-conference Tutorials ------------------------------------------------------------------------------- February 22 and 23, the first two days, are devoted to the tutorial programme. Tutorials will be given by leading international experts covering a select but comprehensive range of topics in the areas. The tutorials offer an excellent opportunity for professional development in computer graphics and related areas. All tutorials are planned to be at an intermediate level, not very introductory nor very advanced, so as to enable a broad range of people to benefit. Five full day tutorials have been planned as follows : ------------------------------------------------------------------------------- Tutorial Programme, Monday, February 22, 1993 09:30hrs to 17:00hrs ------------------------------------------------------------------------------- T1 Computer Animation Nadia Magnenat Thalmann, University of Geneva, Swiss and Daniel Thalmann, University of Laussane, Swiss This tutorial will first present theoretical & practical aspects of computer animation through concepts like image key frame animation, parametric key frame animation and algorithmic animation. It will emphasise 3D computer animation of articulated bodies with a discussion on several important problems to be solved related to realistic human characters in computer generated films. Research issues in development of techniques applicable to specification of tasks using natural language, simulating behaviours and improvement of physical aspects such as shapes, colours, textures, deformation of limbs during motion and facial expressions and deformations will also be discussed. Methods for designing and animating clothes and hair, which are often simulated without autonomous motion in computer generated films, will be presented. Through a discussion on individualised walking model the tutorial will present an innovative way of animating actors at a high level based on the concept of synthetic vision. Each synthetic actor uses a synthetic vision, as its perception of the world, which serves as the unique input to the actor's behavioural model. Finally the tutorial highlights the impact of new 3D devices such as Spaceball, Polhemus and Dataglove on the design of animation of human body and face.

T4 Global Illumination and Image Synthesis Kadi Bouatouch, University of Rennes 1, France, Sumant Pattanaik, National Centre for Software Technology, Bombay, India, and Pierre Tellier, IRISA, University of Rennes 1, France. To attain realism in computer graphics, two main approaches have been adopted. The first make uses of empirical and ad-hoc illumination models, while the other uses fundamental physical laws governing the interaction of light with materials and participating media, and of the characteristics of the human visual system, to produce images which are exact representations of the real world. This tutorial deals with the second approach. The real aspects of material and effects of global lighting can be simulated only with physically based reflection and transmission models, and spectral representation of the emitted, reflected and refracted light powers. The tutorial discusses why a trichromatic approximation is not appropriate when the aim is to produce highly photorealistic images. The objective of this tutorial is threefold. First, it will show how a global illumination model can be derived from physics, optics and photometry. Second, it will provide a collection of information for a complete understanding of colorimetry, visual perception and visualisation. And finally it will present different implementations of global illumination including one pass, two pass and multi pass methods, form factor calculation, fresnel factor calculation, choice of wavelengths and Monte Carlo methods. Kadi Bouatouch is a professor at the University of Rennes, France and a researcher at IRISA. He has been active in the field of geometric modelling and rendering. Pierre Tellier is a doctoral candidate at IRISA, University of Rennes 1, France. He is currently preparing a doctoral thesis in the field of realistic image synthesis. His research interests include physically based global illumination models in computer graphics. Sumant Pattanaik is a senior scientist at the National Centre for Software Technology, Bombay, India. He has just completed the writing of his doctoral thesis in the area of global illumination and visualisation of complex 3D environments. His research interests include global illumination and visualisation in computer graphics. T5 Object Oriented User Interface Development in X/Motif S. P. Mudur, T. M. Vijayraman, K.
