  1. EPI IMAGINE Intuitive Modeling and Animation for Interactive Graphics & Narrative Environment Visite direction 2013

  2. A Computer Graphics group 3D Modeling, Animation, Cinematography • A pluridiscilinary team • Marie-PauleCani(Prof computer science Ensimag/ INPG) • François Faure (Prof computer science UJF) • Stefanie Hahmann (Prof applied-math, Ensimag / INPG) • Jean-Claude Léon (Prof mechanics, Ense3/ INPG) • Olivier Palombi (Prof in anatomy ,UJF) • Damien Rohmer (MdC CPE Lyon) • RémiRonfard(CR1 INRIA) • 14 PhD students • 5 research engineers + 1 computer artist • Administrative assistants : Catherine Bessière (INRIA), Florence Polge (ERC)

  3. Intuitive Modeling and Animation for Interactive Graphics & Narrative Environments Major 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

  4. Creation of Virtual WorldsPractice in the film industry Best research results quickly available but… • Artists do as much as they can WITHOUT computers Shape, motion, stories are drafted on paper, clay, etc. Design stages Digital stages [Pixar, « Geri’s game »]

  5. Creation of Virtual WorldsPractice in the industry Standard software • Direct editing of DoF • (NURBS, subdivision) • Years of training • Spoils 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]

  6. Motion Shape Story Making tools transparent ?Methodology User-centeredperspective on shapes & motion • High-level models embedding a priori knowledge • Generate details from minimal user input • Advanced transfer and editing tools Creating interactive virtual prototypes • Designing & experimenting in the same system • Natural interaction gestures • Real-time response Long term Vision “Magic pen” to seamlessly create shapes, motions & stories

  7. Applications Interactive virtual prototyping, various domains • Civil & mechanical engineering • Natural sciences • Virtual anatomy: ontology, 3D modeling & animation • Plants: high level representations for plants geometry • Art, communication & education • Interactive tools for education • Design tools for artist and the public • Theater: virtual staging & rehearsals • Films & games • Real-time, plausible clothing • Virtual cinematography & film editing

  8. Four scientific axes • High-level models for shapes • In charge: Stefanie Hahmann • Models for real-time motion synthesis • In charge: François Faure • Knowledge-based models for narrative design • In charge: RémiRonfard • Creating and interacting with virtual prototypes • In charge: Jean-Claude Léon
