Slide3

Intuitive 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

Slide4

Creation 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

[

Pixar, « 

Geri

s game »

Slide5

Creation 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]

Slide6

Making 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

Slide7

Applications

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

Slide8

Narrative design 2012-2013

Detecting and naming actors in movies

View-independent model of

actor’s

appearances (

color

) from examples

Compared

to generic

detectors, 20 % better in

recall

, same

precision

Also

useful for live performances
