10º Encontro Português De Computação Gráfica
Actas do 10º Encontro Português de Computação Gráfica 1 – 3 de Outubro 2001 Lisboa – Portugal Patrocinadores de Honra Patrocinadores Organização 10º Encontro Português de Computação Gráfica 1-3 de Outubro 2001 PREFÁCIO A investigação, o desenvolvimento e o ensino na área da Computação Gráfica constituem, em Portugal, uma realidade positiva e de largas tradições. O Encontro Português de Computação Gráfica (EPCG), realizado no âmbito das actividades do Grupo Português de Computação Gráfica (GPCG), tem permitido reunir regularmente, desde o 1º EPCG realizado também em Lisboa, mas no já longínquo mês de Julho de 1988, todos os que trabalham nesta área abrangente e com inúmeras aplicações. Pela primeira vez no historial destes Encontros, o 10º EPCG foi organizado em ligação estreita com as comunidades do Processamento de Imagem e da Visão por Computador, através da Associação Portuguesa de Reconhecimento de Padrões (APRP), salientando-se, assim, a acrescida colaboração, e a convergência, entre essas duas áreas e a Computação Gráfica. Tal como nos Encontros anteriores, o programa está estruturado ao longo de três dias, sendo desta vez o primeiro dia dedicado a seminários por conferencistas convidados e os dois últimos à apresentação de comunicações e de "posters", decorrendo em simultâneo o Concurso para Jovens Investigadores, uma Exibição Comercial e, pela primeira vez, um Atelier Digital. Como novidade essencialmente dedicada aos jovens, realiza-se ainda em paralelo com o Encontro um torneio de jogos de computador. Em resposta ao apelo às comunicações para este 10º EPCG foram submetidos 38 trabalhos, na sua maioria de grande qualidade, tendo sido seleccionadas pela Comissão de Programa, após um cuidadoso processo de avaliação, apenas 19 comunicações; aos autores de 14 dos restantes trabalhos, considerados suficientemente promissores, foi sugerida a sua reformulação e uma nova submissão como "posters". -

However, each platform has its own peculiarities in the way sound is played, the way volume is controlled, where the headphone jack is located, and various other problems.

Interactive Rendering with Coherent Ray Tracing
EUROGRAPHICS 2001 / A. Chalmers and T.-M. Rhyne Volume 20 (2001), Number 3 (Guest Editors) Interactive Rendering with Coherent Ray Tracing Ingo Wald, Philipp Slusallek, Carsten Benthin, and Markus Wagner Computer Graphics Group, Saarland University Abstract For almost two decades researchers have argued that ray tracing will eventually become faster than the rasteri- zation technique that completely dominates todays graphics hardware. However, this has not happened yet. Ray tracing is still exclusively being used for off-line rendering of photorealistic images and it is commonly believed that ray tracing is simply too costly to ever challenge rasterization-based algorithms for interactive use. However, there is hardly any scientific analysis that supports either point of view. In particular there is no evidence of where the crossover point might be, at which ray tracing would eventually become faster, or if such a point does exist at all. This paper provides several contributions to this discussion: We first present a highly optimized implementation of a ray tracer that improves performance by more than an order of magnitude compared to currently available ray tracers. The new algorithm makes better use of computational resources such as caches and SIMD instructions and better exploits image and object space coherence. Secondly, we show that this software implementation can challenge and even outperform high-end graphics hardware in interactive rendering performance for complex environments. We also provide an brief overview of the benefits of ray tracing over rasterization algorithms and point out the potential of interactive ray tracing both in hardware and software. 1. Introduction Ray tracing is famous for its ability to generate high-quality images but is also well-known for long rendering times due to its high computational cost. -
