It reminds me a lot of the real world construction technique of using a Monolithic Dome. Check it out. http://www.monolithic.com

Hello-
New guy here. This is my first post actually. Just wondering where this rock is located. If its famous enough, there mught already be some 3D data available on it, in the form of DEM data, survey work, or even some simple "terrain" image from Google Earth itself. You might also be able to work it out with enough images using Photomatch. Start off with a square "blocky" version and then refine it later. Just a thought. Good luck with it.
