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.
