Addressing Incomplete Building Representation on Steep Terrain

[geobuilding]

When placing buildings above the terrain, if the terrain slope is steep, the buildings may appear incomplete with some roof surfaces missing.

This is because there may be a point inside the outline where the terrain height is greater than the height of all vertices. Should we consider setting sampling points within the outlines? By doing so, we can obtain the minimum and maximum terrain heights, which could potentially result in complete buildings. This is just my speculation, and I am looking forward to finding a good solution.
