Triangular Irregular Networks are vector-based lines with three-dimensional coordinates. Using Delanuay triangulation, TINs are good when points are irregular distrubuted geographically… The downside with TINs is that you often can’t run tools for slope, aspect, flow networks, etc

That’s another way to put it. But it’s also true that vegetation isn’t extruding and is simply elevation of the bare ground
