Scientific focus Modeling & Visualizing Nature

• Fascinating problem (vegetal, mineral, animal kingdoms)

• Many applications, from realism to real-time– 3D feature films, Special effects, Video games

– Virtual prototyping : geology, energy, cosmetics…

– Pedagogical Simulators : environment, aeronautics, surgery…

Scientific focus Modeling & Visualizing Nature

Extreme complexity Nb of elements, shape, aspect, motion and deformation

– Use knowledge form other disciplines

– Specific methodology to combine efficiency and realism

1. New fundamental tools2. Application to specific natural scenes

Contributions1. New fundamental tools

• Geometry– New shape representations

– Interactive deformations

• Animation– Motion control from video analysis

– Physically-based simulation

• Visualization of massive data-sets– Multiresolution analysis & adaptive rendering

• Realistic rendering– Textures, shaders, point-based rendering

Contributions2. Application to specific natural scenes

• Mineral world– Animation of lava-flows, sea, streams

– Simulation of water, smoke, clouds

• Vegetal world– Real-time rendering of forest

– Animating meadows (grass, trees)

• Animal world– Wild animals animated from video

– Virtual humans: hair, skin, muscles, clothes

– Real-time organs for surgery simulators

Virtual worlds: recent results

• Clothing from sketches

[EG 2006, IEEE CGA, SGP 2007]

with Brown & UBC

• Super-helices [SIGGRAPH 2006]Accurate dynamics of straight to curly hair

• Kamelelon with the Museum

Virtual worlds: recent results

• Realistic Clouds in Real-time [I3D 2008]

• Fast hydraulic erosion of terrains[Pacific Graphics 2007]

• Modeling & rendering large natural scenes

[EG 2008]

Virtual reality?

• Ongoing work on Virtual sculpting
