During this defense, I’ll present part of my work on computer graphics applied to the creation of animated films, and more specifically on how digital tools can help artists reproduce the distinctive characteristics of traditional 2D animation, both in terms of appearance and movement. This work is part of a research trajectory that has gradually shifted from expressive rendering to the stylization of form and movement, and finally to assisting in the creation of sketched 2D animations. A common thread runs through this work: placing artistic control at the heart of the design of the proposed solutions, in order to offer artists interactive tools compatible with their professional practices.
Finally, I’ll outline several perspectives on the coherent integration of 2D and 3D content. To achieve this, beyond technical challenges, a central scientific question remains: how to characterize the perceptual cues that distinguish movements in traditional 2D animation from those generated by 3D animations.
