A helper class for interpolating between times during particle tracing.
vtkTemporalInterpolatedVelocityField is a general purpose helper for the temporal particle tracing code (vtkParticleTracerBase)
It maintains two copies of vtkCachingInterpolatedVelocityField internally and uses them to obtain velocity values at time T0 and T1.
In fact the class does quite a bit more than this because when the geometry of the datasets is the same at T0 and T1, we can re-use cached cell Ids and weights used in the cell interpolation routines. Additionally, the same weights can be used when interpolating (point) scalar values and computing vorticity etc.
- Warning
- vtkTemporalInterpolatedVelocityField is probably not thread safe. A new instance should be created by each thread.
-
Datasets are added in lists. The list for T1 must be identical to that for T0 in structure/topology and dataset order, and any datasets marked as static, must remain so for all T - changing a dataset from static to dynamic between time steps will result in undefined behaviour (=crash probably)
