What does `wedge` means in vcglib?

In the Visualization and Computer Graphics Library (VCG for short), there's a concept as wedge.
For example, vcg::face::WedgeTexCoord and vcg::face::WedgeColor. What does wedge mean?

wedge means one of the corner portion of a triangle. You can imagine that attributes of a mesh (color, normal texture coords) can be stored there in a way that can allow to manage easily discontinuities and smooth variations. In this way a face store the colors for his three vertices independently.

I think the first widely use of this term is in this paper:

Hoppe, Hugues. "New quadric metric for simplifying meshes with appearance attributes." Proceedings Visualization'99 (Cat. No. 99CB37067). IEEE, 1999. (PDF)
