A sphere primitive for the planet. As you get closer, a mesh of the area
visible from the ship...a few hundred thousand triangles, maybe a
million. Once you get close to the canyon, switch to a high level of
detail mesh, the detail will probably require a million or so. Then back
through a medium LOD mesh (maybe the same as the one on incoming, maybe
different) and then switch to the sphere again. 2 or 3 meshes, none
having anything near 100 million triangles. You could set things up so
you have one bigger mesh with variable amounts of detail, highest in the
canyon...simpler but less efficient, but nowhere near as bad as your
idea of using a full-resolution mesh of an entire freaking planet.
*That* is just wasteful on current systems, even if you have the RAM for
it.
