I'm not sure I understand this...trace() is not scale dependant. It 
takes a starting point, an object, and a direction, and intersects the 
ray defined by the start point and direction with the object. The size 
of the surface or distance of the intersection don't matter.

Hmm, you could probably do a nearly infinite flying animation by moving 
the containing box for the landscape along with the camera, and using 
the noise3d() function instead of rand() to place the rocks and trees. 
Or you could just make a really big landscape...
