Algoritmos paralelos para o paradigma de pertinência interior/exterior

Abstract in Portuguese
O teste interior/exterior, que especifica se um ponto é parte de um objeto matematicamente bem definido, é um problema crucial em computação gráfica. Algoritmos baseados nesse teste podem ser executados para diversis pontos em paralelo, uma vez que não há dependência entre as computações para diferentes pontos. Este dissertação apresenta uma variedade de implementações paralelas para operações de preenchimento e traçado de linhas para combater a principal desvantagem desse tipo de algoritmo: sua lentidão em uma implementação seqüencial em software para edição e manipulação interativa

Abstract in English
The point containment predicate which specifies if a point is part of a mathematically well-defined object is a crucial problem in computer graphics. Point-driven algorithms can be executed for several points in parallel as there is no interdependence among the computations for different points. This work presents a variety of parallel implementations for filling and stroking operations to counteract the main disavantage of the point-driven algorithm: its slowness on a standard uniprocessor software implementation for interactive editing and manipulation
