hippomaps.utils.laplace_solver

hippomaps.utils.laplace_solver(faces, init, maxiters=10000.0, conv=1e-06, cores=8)

Solves the Laplace equation along vertices of a surface.

Parameters:

• faces (Faces of a surface mesh.) –

• init (Initial vertex-wise values. Source(s) should have a value of 0, Sink(s) should have a value of 1. NaN values will be masked. Time required scales with the number of unmasked vertices.) –

• maxiters (int, optional) – Maximum iterations to run. Default is 1e4.

• conv (float, optional) – Convergence criterion. Default is 1e-6.

• cores (int, optional) – Number of CPU cores to use (per iteration). Default is 8.

Returns:

• LP (Laplace solution (vertex-wise).)

• change (sum of absolute changes per iteration (should converge towards 0))
