Calculate surface area of a "surf" object by vertex or face. Surface
area calculation by vertex matches the Workbench command
"-surface-vertex-areas".
surf_area(surf, by = c("vertex", "face"))Vector of surface areas by vertex or face, in the same order
as how the vertices or faces are listed in surf. The units are the
square of the units of surf$vertices.
The "surf" object.
"vertex" or "face". For "vertex", the result
is the area associated with each vertex: the sum the area of each triangular
face it is a part of, divided by three. For "face", the result is
the surface area of each face.
