## Detailed Description

template<typename ScalarT = float>
class openvdb::v10_0::tools::EnrightField< ScalarT >

Analytical, divergence-free and periodic velocity field.

Note
  Primarily intended for debugging!

Warning
  This analytical velocity only produce meaningful values in the unit box in world space. In other words make sure any level set surface is fully enclosed in the axis aligned bounding box spanning 0->1 in world units.

## Member Function Documentation

## operator()() [1/2]

template<typename ScalarT = float>

VectorType operator() | ( | const Coord & | ijk,
|  | ValueType | time ) const

inline

Returns
  the velocity at the coordinate space position ijk

## operator()() [2/2]

template<typename ScalarT>

math::Vec3< ScalarT > operator() | ( | const Vec3d & | xyz,
|  | ValueType | time ) const

inline

Returns
  the velocity in world units, evaluated at the world position xyz and at the specified time

## transform()

template<typename ScalarT = float>

math::Transform transform | ( |  | ) | const

inline

Returns
  const reference to the identity transform between world and index space

Note
  Use this method to determine if a client grid is aligned with the coordinate space of this velocity field
