34 ## The face color of each cell of the mesh is determined by interpolating
35 ## the values of @var{c} for the cell's vertices. Contrast this with

38 ## @code{shading} modifies an attribute determining the manner by which the
39 ## face color of each cell is interpolated from the values of @var{c},
40 ## and the visibility of the cells' edges. By default the attribute is
41 ## "faceted", which renders a single color for each cell's face with the edge
