Description

Description:
Returns the position on landscape (PositionAGL) corresponding to the given point on screen (in UI coordinates).
This command performs an intersection with the ground/water surface, from the camera position along the screenToWorldVector vector. In other words, it's similar to doing:
private _p1 = AGLtoASL positionCameraToWorld [0,0,0]; // camera position ASL private _vector = screenToWorldVector _screenPos; // "aim" vector private _p2 = _p1 vectorAdd (_vector vectorMultiply viewDistance * 2); // the ray doesn't go beyond 2 * view distance ASLtoAGL terrainIntersectAtASL [_p1, _p2]
