Detailed Description

template<class TPointContainer, class TWeightContainer>
class itk::BarycentricCombination< TPointContainer, TWeightContainer >

Class that computes the barycentric combination of an array of N points

An array of (N-1) values is expected to weight the contribution of the first (N-1) points, the weight of the Nth point is computed to ensure that the N weights sum 1.

This method computes:

\[ \overrightarrow{P}= \sum_{i=1}^{N-1} w_i * \overrightarrow{P}_i + \left(1- \sum_{i=1}^{N-1} w_i\right) * \overrightarrow{P}_N \]

The points are expected to be stored in an itkContainer class like itk::VectorContainer, responding to the Begin(), End(), Value() API.

The weights are expected to be stored in any array-like container having a operator[i].
