Description of template class 'LocalConvolutionNormalVectorEstimator'
A model of CNormalVectorEstimator.
To each $n-1$ signed surfel, an elementary inward normal vector can be defined. At a given surfel, this estimator will compute the convolution of elementary normal vector of neighboring surfels using a breadth-first propagation around the given surfel.
The neighboring is parametrized by a given topological radius R. The weight kernel function maps displacment vectors to a continuous weights.
