std::pair< bool, Ogre::Real > Collisions::intersectsTerrain ( Ogre::Ray ray )

Checks whether a Ray intersects the terrain.

ray	The ray that is checked for an intersection with the terrain.

Returns: Pair of whether an intersection was found and the distance to the point of the intersection. The distance is measured in the ray's direction vector's unit and cannot be larger than 1.0.
