Algorithm behind paricle to mesh wrapper

1

Can you please let me know what algorithm goes behind to find the mesh from particle information? What algorithm goes behind the below code?

warper = MeshWarper()
warper.generateWarp(reference_mesh, median_particle)
mean_mesh = warper.buildMesh(median_particle)

It uses LibIGL’s biharmonic shape deformation:
