A dissertação apresentada faz uma análise a um processo indispensável na produção de
qualquer projecto de animação 3D, a iluminação. A análise terá como base o leque de
ferramentas que o Maya dispõe para o efeito e a forma como a luz se porta em cenários
distintos. A investigação acompanhou o Projecto Final do Mestrado em Animação por
Computador, que teve inicio em Setembro de 2009 e terminou em Julho do ano seguinte,
dando origem à curta metragem “Holidays o’Nice”.
Na parte mais teórica deste trabalho é de realçar a pesquisa efectuada sobre a física das cores
como a sua medição e reprodução, sendo um tema completamente desconhecido para mim e
que despendeu de algum tempo para o perceber.
É também apresentada uma análise detalhada do trabalho prático que descreve ao pormenor
todas as fases de pré-produção, produção e pós-produção por que a curta “Holidays o’Nice”
passou durante o período de tempo da disciplina na qual estava integrada.
O trabalho, na sua globalidade, dá uma ideia de como a iluminação é importante para o
resultado final de uma imagem gerada por computador, tentando explicar os passos que o
iluminador precisa de seguir, desde a posição das luzes em sítios estratégicos até ao processo
final de render que tem como resultado a imagem.
No que diz respeito ao trabalho prático, pude concluir que, das três fases de produção de uma
curta-metragem deste género, a pré-produção assume um papel importantíssimo para o
resultado positivo de qualquer animação em 3D e que, se esta for seguida consoante a sua
planificação, a carga de trabalho irá ser mais fácil de acompanhar ajudando os autores a não
se perderem em coisas que possivelmente depois nem irão ter grande relevo no filme.
This thesis analyses a very important process in the production of any 3D animation project: lighting. This essay will be based on the set of tools Maya has for that effect and the way that light behaves in different sceneries. This investigation has accompanied the Computer Animation Master’s Degree Final Project, which started on September 2009 and finished on July the next year, giving rise to the short “Holidays o’Nice”. In the theoretical part of this work it must be emphasized the research on the physics of colour, its measuring and production, completely unknown to me and that took some time to be understood. This work will also make a detailed description of the practical part of the project, showing in detail all the phases of pre-production, production and post-production through which the short “Holidays o’Nice” has passed during the period of the chair in which it was integrated. This essay, in its whole, gives an idea of the importance of lighting to the final result to a computer-generated image, trying to explain the steps the designer has to follow, from the setting of light in strategic places to the final process of render that leads to image. In what concerns the practical work, I came to the conclusion that, among the three phases of of a short production of this kind, pre-production takes a very important role to the result of any 3D animation and that, if its plan is strictly followed the workload will be easier to follow, helping the authors not to lose themselves in things that probably will not have great significance to the movie.
