Detailed Description

template<typename ScalarT = float>
class openvdb::v9_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

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

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

inline

Returns

the velocity at the coordinate space position ijk

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
