terrain_cell

The height of the ground inside one cell of a landscape's lattice of samples (zero_terrain_cell_height): the cell's two triangles, split along the diagonal from its +Z corner to its +X corner. It is the surface a Terrain's collider holds, its mesh draws and terrainHeightfield.cellHeight answers, so a kernel that reads a landscape's height between its samples through it puts a point on that same ground.
