在osggis官网上找到了答案:
osggis_makelayer will clamp lines and points to the terrain, but polygons only get clamped at their points (the entire polygon area does not conform to terrain). Try extruding polygons with --extrude-height. Or, you can generate a flat geometry model from your polygons and then project it onto the terrain with osgSim::OverlayNode. |
