Abstract : In this document I present a summary of some of my research and also my experience with administrative research management tasks. The research presentation is followed by the related significant publications and at the end of the document, I have included the complete list of my publications. I have conducted research over the last nine years and a unifying theme is the challenge of geometric modeling of complex shapes. Nowadays, images are becoming more and more important in our everyday life. Display devices such as screens, mobile phones, tablet-PCs, notebooks, are ubiquitous. Requests for the production of visual content are thus increasing and an efficient solution relies on the generation of virtual content. This requires the use of very efficient but intricate and complicated modeling software, only accessible to professionals or enthusiast users. One of the main reason is that no model for representing shape supports fast and immediate rendering, robust editing and simple implementation. Some methods suffer from numerical instability or do not currently support intuitive user interaction. In fact, there is no stable modeling methodology that enables the rapid development of models that is both efficient and intuitive to use for non-expert users. In the first chapter I present some of my research results on subdivision surfaces, a well-known and recognized surface representation for its flexibility and efficiency in geometric modeling applications. I discuss the advantages and weaknesses with respect to the problems mentioned above. This leads to my investigations into sketch based modeling, an efficient contour based technique with user-friendly interactions for shape modeling. This work demonstrates the usefulness of volumetric representations (implicit surfaces) and I present the recent research we have done for improving their control and enhancing their efficiency in modeling situations. We conclude with our perspectives and projects around volumetric shape representations.
