EVASION Virtual Environments for
Modeling, Animating & Rendering
Natural Scenes
INRIA & Grenoble University
Contact: Marie-Paule Canihttp://evasion.imag.fr/

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
![Page 12: REVES research group](https://reader036.fdocuments.net/reader036/viewer/2022062409/56814894550346895db5a972/html5/thumbnails/12.jpg)
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
