Abstract : As virtual content continually grows in quantity and quality, new challenges arise.Amongst others, generating and manipulating 3D shapes and animations have become intricate tasks.State of the art methods attempt to hide this complexity through complex tools, which exploit content semantics for running optimization procedures, yielding constraint matching outputs.However, the control offered by such methods is often indirect, object-specific, and heavy, which imposes long trial-and-error cycles and restrains artistic freedom.The focus of this thesis is twofolds:First, improving user control through interactive and direct content manipulation;Second, enlarging the spectrum of manipulable content with innovative or generic content representations.We introduce three new mehods related to 3D shapes design:A part-based modeling tool allowing to generate assembly shapes with semantic adjacency constraints;A painting tool for distributing objects in a 3D scene;And a grammar-based hierarchical deformation paradigm, enabling the interactive deformation of complex models.We also propose two methods related to the design of animated contents: A vectorial editing tool to synthesize consistent waterfall scenes;And finally a sculpting method enabling to design new liquid animation from examples.
