10: Level Set and PDE Methods for Computer Graphics
Sunday, Full Day
8:30 am – 5:15 pm
Room 206
The underlying concepts, equations, and numerical methods
for level set and partial differential equation (PDE)
methods, and how they may be used in a variety of graphics
applications, including image inpainting, pattern formation,
3D curve computation, 3D shape reconstruction, surface
editing, image and shape morphing, and fire and water
simulation.
Prerequisites
Knowledge of calculus, linear algebra, and computer
graphics, including geometric modeling and computer
animation. Some familiarity with differential geometry,
differential equations, numerical computing, and image
processing is strongly recommended but not required.
Topics
Fundamentals (level set and PDE concepts, derivation
of level set equations and other PDEs, numerical methods).
Practical considerations (building a level set library,
importing conventional geometry). Applications (image
inpainting, pattern formation, curve computation, image
and volume processing, shape reconstruction, image and
volume segmentation, image and shape morphing, surface
editing, dynamic visibility, anistropic diffusion, and natural phenomena
simulation).
