Slide3Intuitive Modeling and Animation for
Interactive Graphics & Narrative EnvironmentsMajor Issue : demand for more and more complex scenes
Armies of Computer Artists during several years?Or automatic creation … with little control ??
Scientific focus:
Creation tools for animated virtual worlds
Applications to films & games, engineering, other sciences, general public
Slide4Creation of Virtual Worlds
Practice in the film industryBest research results quickly available but…Artists do as much as they can WITHOUT computers Shape, motion, stories are drafted on paper, clay, etc.
Digital stages
Design stages

Slide5Creation of Virtual Worlds
Practice in the industryStandard software Direct editing of DoF (NURBS, subdivision) Years of trainingSpoils creativity!
Grand challenge? “Make tools as transparent to the artists
as special effects were made transparent to the public!
”[Rob Cook, Technical director Pixar, 2009]
Slide6Making tools transparent ?
MethodologyUser-centered perspective on shapes & motionHigh-level models embedding a priori knowledge
Generate details from minimal user inputAdvanced transfer and editing toolsCreating interactive virtual prototypesDesigning & experimenting in the same system
Natural interaction gestures
Real-time response
Long term Vision
“Magic pen” to seamlessly create shapes, motions & stories
Shape
Story
Motion
Slide7Applications
Interactive virtual prototyping, various domainsCivil & mechanical engineeringNatural sciencesVirtual anatomy: ontology, 3D modeling & animationPlants: high level representations for plants geometry
Art, communication & education Interactive tools for educationDesign tools for artist and the publicTheater: virtual staging & rehearsals
Films & games
Real-time, plausible clothing
Virtual cinematography & film editing
Slide8Four scientific axes
