Dear all,
I have the following snippet of code.
const unsigned int dim = 2;
double factor = 1./std::sqrt(dim);
Point<dim> p1test{factor, -factor};
Point<dim> p2test{factor, factor};
Point<dim> p3test{-factor, -factor};
std::vector<Point<dim> > surrounding_points;
surrounding_points.push_back(p1test);
surrounding_points.push_back(p2test);
surrounding_points.push_back(p3test);
std::vector<double> surrounding_weights(3);
surrounding_weights[0] = 0.5;
surrounding_weights[1] = 0.25;
surrounding_weights[2] = 0.25;
auto new_vertex = spherical_manifold.get_new_point(
ArrayView<Point<spacedim>>(&surrounding_points[0],
surrounding_points.size()),
ArrayView<double>(&surrounding_weights[0],
surrounding_weights.size()));
I would expect the new point to coincide with the original one, but instead
it collapses on the second. Looking into the code of spherical manifold the
associated angles are: 7/4 pi, 1/4 pi and 5/4 pi. From this representation
I would expect the projected point to be at 5/4 pi.
I really don't understand this behavior of SphericalManifold, do you have
an explanation?
Bests,
Nicola
