Do I understand this correctly? Only the "high resolution" vertices will be used and the geometry will simply reference the appropriate subset of vertices based on the level of detail? Therefore, only 1 OceanTile object would be needed (for the highest level) and the other levels-of-detail wouldn't be needed. Then the MipmapGeometry::updatePrimitives call would just update the geometry to references the "appropriate" high-level" vertices based on the current resolution. I assume the same would be true for the Normals where only the normals for the high resolution would be used. Your TilePrimitives example kind of brushes over the Normals and the existing OceanTile::computeNormals seems to be resolution dependent. Do I have this correct? Just trying to understand what you are planning.
