RingLod

Defined in: packages/marine/src/webgpu/RingLod.ts:46

The sea as a geometry clipmap (Losasso and Hoppe 2004): square rings around the centre, each with twice the vertex spacing of the one inside it, every level snapped to its own grid so that vertices stay put on the sea as the centre moves. Snapping leaves the hole in each ring one cell off from the level inside it on two sides; thin trims fill it. The outer band of every level morphs onto the coarser grid, so the rings meet without cracks.

Every ring is one mesh, as is each trim: about three draw calls a level, and the same triangles however the centre moves.
