RESUMO

With the growing popularization and increase of performance of personal computers, the Graphic Computation won new encouragement. Strongly impelled by the industry of entertainment, it is probably one of the branches of the computation that has been developing faster in the last years. This fast development has been generating new challenges to the students and teachers in the area for it demands a great effort in learning and updating. This work intends to show that the learning of Graphic Computation can be done in an interactive way, by means of the computer itself For such, instead of the traditional study books, it will be shown that texts written in HTML and with hyperlinks (automatic connections among pages, sending the reader from underlined words to related subjects with a mouse click) can be more efficient. To show the viability of this new approach, there were chosen some areas of the Graphic Computation that, although not among the most basic ones, are of difficult learning because they are hardly found concentrated in the literature or have complex concepts. That is the case of interpolation, where knowing how to use an interpolador is not enough, once you need to analyze the context to select the most appropriate interpolador for each case. Another vast theme that some years ago was even independent from Graphic Computation is Image Processing. In this work only a few topics from the vast area of Image Processing will be shown. Finally other topic that requests analysis and reflection is Three-dimensional Objects Manipulation. In this case also, just a small section of the subject will be shown. It would have been interesting to present a great number of examples and implementations, which was cogitated in the beginning of the works. Nevertheless, due to the high cost in developing implementations, which were done by the author especially for this work, he opted for presenting only a small number of applications. This option was suggested by the Committee that evaluated the Proposal of Dissertation, where the examining bank opted indeed for limiting the the work to the topics presented, once the target was a Master Degree Thesis and not a commercial software project. It is hoped that the text will be used by teachers and students with some knowledge of Graphic Computation, specially of C++ and/or JAVA, as a complementary resource or reference.
