In CityEngine, I have a GIS dataset that includes the shapes of roofs on their proper altitudes, meaning that the shapes are in the air (they have x, y and z values). I also have the terrain surface and a height for each shape/building (an average height probably).
Any idea of how I can properly generate the buildings using that information?
I have tried extruding downwards but the results are not very good. Not that a number of roof shapes are inclined and I don't want to lose that amount of detail.
I was thinking of projecting the roof shapes to the terrain and then extruding the copied shapes to the original roof shapes. Anyone know if this is somehow possible?
