About the Book

A Realidade Aumentada é um campo de pesquisa que trata do estudo de técnicas para integrar informações virtuais com o mundo real. Algumas aplicações de Realidade Aumentada requerem fotorrealismo, onde os elementos virtuais são tão coerentemente inseridos na cena real que o usuário não consegue distinguir o virtual do real. Para a síntese de cenas 3D existem diversas técnicas, entre elas o ray tracing. Ele é um algoritmo baseado em conceitos básicos da Física Ótica, cuja principal característica é a alta qualidade visual a um custo computacional elevado, o que condicionava a sua utilização a aplicações offline. Contudo, tirando proveito do poder de paralelismo das GPUs, esta técnica pôde ser utilizada em aplicações de realidade aumentada, que são de tempo real. Este livro propõe um conjunto de técnicas para renderização fotorrealística de tempo real utilizando o ray tracing em aplicações de Realidade Aumentada. Foram propostas também algumas técnicas utilizando o dispositivo Kinect, da Microsoft, que possibilita a obtenção de informações reais da cena, em tempo real, eliminando a necessidade de se conhecer previamente os objetos pertencentes à cena real.
