I'm modelling entire planets, which are unfortunately round, so the
heightfield primitive isn't much use to me. I've previously been using
isosurfaces but they're just too horrifically painfully slow,
particularly if I want to avoid render artifacts. Going for a polygon
mesh is a new improved system to try and avoid all that.

One day someone's going to come up with a way of storing efficient,
interpolatable spherical heightmap data without the distortion involved
in forcing it into a 2D matrix...
