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 screenToWorldDirection vector up to viewDistance for terrain intersection and 2 * viewDistance for water intersection. In other words, it is similar to doing:

private _p1 = AGLToASL positionCameraToWorld [0, 0, 0]; // camera position ASL private _vector = screenToWorldDirection _screenPos; // "aim" vector private _p2 = _p1 vectorAdd (_vector vectorMultiply viewDistance * 2); // the ray does not go beyond 2 * view distance ASLToAGL terrainIntersectAtASL [_p1, _p2]
