Member Function Documentation

VectorType operator() ( const Vec3d &  xyz,
ValueType   
) const
inline
Returns
the interpolated velocity at the world space position xyz
Warning
Not threadsafe since it uses a ValueAccessor! So use one instance per thread (which is fine since its lightweight).
VectorType operator() ( const Coord &  ijk,
ValueType   
) const
inline
Returns
the velocity at the coordinate space position ijk
Warning
Not threadsafe since it uses a ValueAccessor! So use one instance per thread (which is fine since its lightweight).
const math::Transform& transform ( ) const
inline
Returns
const reference to the transform between world and index space
Note
Use this method to determine if a client grid is aligned with the coordinate space of the velocity grid.
