Hi Andrew,
I restructured the package a bit for 1.0 :
Mesh.ToPolySurface is now multithreaded and replaces the
“Topography.ToPolySurface” node. This way you can also process meshes
obtained through other means and still handle toposurfaces by first
extracting their mesh with the built-in “Topography.Mesh” node.
This is an exert from the changelog, which you can find here:
