Detailed Description

Defines two simple wrapper classes for advection velocity fields as well as VelocitySampler and VelocityIntegrator.

Author

Ken Museth

DiscreteField wraps a velocity grid and EnrightField is mostly intended for debugging (it's an analytical divergence free and periodic field). They both share the same API required by the LevelSetAdvection class defined in LevelSetAdvect.h. Thus, any class with this API should work with LevelSetAdvection.

Warning

Note the Field wrapper classes below always assume the velocity is represented in the world-frame of reference. For DiscreteField this implies the input grid must contain velocities in world coordinates.
