  One of the most influential early works in graphic statics is one of Maxwell,
where he introduced the idea of a discontinuous stress function and the use of
a 3D projective polarity for a planar problem. A recent work gave an analytical
description with the goal to provide explaining power, treating planar forces
as linear functionals (moment functionals) forming a 3D vector space, so force
and form diagrams of planar problems can be interpreted in a 3-dimensional way.
The linear combination of these moment functions can naturally be used as a
discontinuous stress function since the Airy stress function is known to
correspond to moments of planar forces. The main contribution of this work is
to present a dimension independent way of treating forces as functions, that
returns the known stress-functions of planar and spatial graphic statics. This
is done by relying on the multi-linear function definition of
Grassmann-algebra.
