It is possible to approximate perspective using piecewise affine transformations. It is certainly possible to match the perspective transformation at the vertices of the subdivisions, and only be somewhat off within.
With 6 degrees of freedom, you can only fit 3 2d points at a time. Triangulation causes the errors shown in the article, hence why subdivision is needed.
