) const

Computes weights allowing to compute the deformation gradient (deformed basis) at each vertex during the simulation, for a volumetric object. For each vertex, computes the weights associated with each edge around the vertex, so that the weighted sum of the edges corresponds to the identity. The current configuration is taken as reference. During the simulation, the weights and edge indices can be used to compute rotated and deformed bases for each vertex

The output vectors contain the concatenation of the values for each vertex. The weights are computed using a pseudo-inverse of the edge matrix: w_i = Vt_i.(V.Vt)^{-1}.Id3

Parameters
numEdgesnumber of edges attached to a vertex
edgesattached to the vertices
weightsassociated with the edges. Each Vec3d represents the contribution of the associated edge to x,y and z of the deformed basis.
