It's not J, but FWIW Dyalog APL apparently can boast this realistic, immersive simulation of some piece of Finnish  coastline. The 3D engine is an external dependency, but supposedly everything else is straight APL:

Since the core of that project is taking large amounts of data, scattered in lots of non-uniform formats, and munging it into a concrete realtime visualization, you might find it interesting/inspiring/helpful/whatever.
