class itk::TimeVaryingBSplineVelocityFieldTransform< TParametersValueType, VDimension >
Integrate a time-varying velocity field represented by a B-spline control point lattice.
Diffeomorphisms are topology-preserving mappings that are useful for describing biologically plausible deformations. Mathematically, a diffeomorphism, \( \phi \), is generated from a time-varying velocity field, v, as described by the integral equation:
\[\phi(t_b) = \phi(t_a) + \int_{t_a}^{t_b} v(\phi(t),t) dt
\]
In typical registration applications it is computationally more efficient to sample the B-spline transform to its corresponding displacement field. Therefore, the user needs to specify the domain parameters of that displacement field using the following functions:
SetDisplacementFieldSpacing() SetDisplacementFieldOrigin() SetDisplacementFieldSize() SetDisplacementFieldDirection()
It's important that these parameters match up with the fixed parameters of this transform which are defined as the parameters of the (N+1)-D B-spline grid representing the continuous velocity field. This control point lattice is set using SetTimeVaryingVelocityFieldControlPointLattice() or it can be created by setting the fixed parameters.
Note: For readability of the code, it is important to note that we store the control point lattice in the m_VelocityField variable since they are of the same type. It's only when we call IntegrateVelocityField() that a sampled velocity field is created from the control point lattice.
