The terrain is a 1024×1024 height grid made from randomly stacked squares. Cells with the same slope are merged into panels of up to 16×16, so there is less to draw. The merging and the drawing are both split across every CPU core, which share one depth buffer. A source comment notes that the buffer is unlocked, "so we get some glitches."
