Node count:

Press one of the buttons to recompute a simulated LOD subdivision using that projection.

Note:

• LOD is strictly 2D, based on the camera look-at position at the time you press the button.
• "Bent Mercator" is Mercator, except that latitude [-90,90] is mapped into [-85,85] for the projection math, and therefore it covers the poles (but is not conformal, unlike regular Mercator).
• Cube Cell's LOD calculation is approximate, and different from the others, so the node counts aren't directly comparable.
