Em computação gráfica, diversos problemas consistem na análise e manipulação da geometria de superfícies. O operador Laplace-Beltrami apresenta autovalores e autofunções que caracterizam a geometria de variedades, proporcionando poderosas ferramentas para o processamento geométrico. Nesta dissertação, revisamos as propriedades espectrais do operador Laplace-Beltrami e propomos sua aplicação em computação gráfica. Em especial, introduzimos novas abordagens para os problemas de segmentação semântica e geração de atlas em superfíciesMany applications in computer graphics consist of the analysis and manipulation of the geometry of surfaces. The Laplace-Beltrami operator presents eigenvalues and eigenfuncitons which caracterize the geometry of m...
