Project vectors to the edges of the mesh.

Consider a numpy array edge_vectors whose rows provide a vector for each edge in the mesh. For each edge, project_edge_vector computes the dot product between a vector and the corresponding edge’s unit tangent vector. That is, project_edge_vector projects the vectors in edge_vectors to the edges of the mesh.

edge_vectors(n_edges, dim) numpy.ndarray

Numpy array containing the vectors that will be projected to the mesh edges

(n_edges) numpy.ndarray of float

Dot product between each vector and the unit tangent vector of the corresponding edge
