The present invention relates to a method for rendering a multi-resolution terrain using GPU tessellation.A method for rendering a terrain using GPU tessellation according to an embodiment of the present invention may include: generating a quad patch to which an inner tessellation factor and an edge tessellation factor are allocated by using a quadtree including a parent node and child nodes; generating a base mesh b using the quad patch; and restoring a terrain by applying a displacement map to the base mesh.
