Aim: Class for the computation of the a speed value at some point p, from the available distance values and speed values of some points lying in the 1-neighborhood of p (ie. points at a L1-distance to p equal to 1) in order to extrapolate a speed field in the normal direction to the interface.
Description of template class 'SpeedExtrapolator'
The computed value is such that the dot product of the gradients of the speed function and of the distance function is zero, ie. \( \nabla S . \nabla \Phi = 0 \).
It is a model of CPointFunctor.
| TDistanceImage | model of CImage used for the mapping point-distance value |
| TSet | model of CDigitalSet for storing points whose distance value is known |
| TSpeedFunctor | model of CImage used for the mapping point-speed value |
