Chair: Luiz Marcos G. Gonçalves (UFRN)


Prof. Dana Ballard, Rochester University – USA

Recent advances in graphics rendering have allowed the modeling of visual
systems for artificial graphics "people" or humanoids. The humanoids exist in a graphics world. They have eye, head and posture movements, and see stereo images of the
rendered world. In order to behave appropriately they must process these images
in real time and use them to control body movements. Sample behaviors are:
walking along a sidewalk in an urban setting while avoiding other pedestrians and
crossing streets safely. The use of humanoids allows the experimentation with
dynamic control strategies that incorporate learning algorithms. In addition, the
artificial environment offers speed and flexibility in algorithm development not
possible in the real-world. The presentation will describe the features of this
new research paradigm.

Chair: Soraia Raupp Musse (UNISINOS)


Prof. Rick Parent, Ohio State University – USA

One of the 'holy grails' for Computer Animation has been modeling and
animating a synthetic human figure indistinguishable from real life.
There are obvious applications for such a capability in the entertainment
industry. But such technology can also be used in creating more realistic
training environments, more natural user interfaces, and improved educational
material. Great strides have recently been made towards this objective by both
industry and academia. By combining knowledge from such diverse fields as
medicine, art, biomechanics, forensic science, and robotics, there has
been a greater understanding (and appreciation) of the complexity of the human
form. One only has to look at recent films to see how synthetic human figure
modeling and animating have evolved. However, there are still problems to be
overcome in order to satisfy a Turing-like test for synthetic humans.
This talk will review the progress made, the techniques used, the relevant
research at Ohio State, and the issues yet to be resolved.

It is frequently claimed that the games industry drives the development of personal computing. And with a market that will reach U$ 31 billion this year, more and more companies are investing heavily on R&D (in 1999, the games industry surpassed the pharmaceutical industry in that aspect). This lecture will present what is next on the game development frontier, and also the latest already in use in game development studios around the world.

A Strategy for Rendering the Sky and its Elements in Games

Márcio Pereira de Araújo, Waldemar Celes (TecGraf, PUC-Rio) 

A good rendering algorithm for the sky and its elements (clouds, sun, moon, and stars) is essential to add realism in computer games that make use of external scenarios. As precise and physically based simulation of these effects can be computationally expensive, several games use artifacts to render the sky as textures mapped to geometrical supports, such as skydome and skybox. This paper presents another simple strategy to render the sky and its elements. The proposal facilitates sky modeling and presents good performance. It also allows the rendering of simple dynamic effects, such as the movement of clouds, star shininess and environment state transition.
