METHOD FOR RENDERING TERRAIN

摘要

The present invention relates to a method for rendering topography using GPU tessellation. According to an embodiment of the present invention, a method for rendering topography using GPU tessellation may include the steps of: 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 a child node; generating a base mesh by using the quad patch; and restoring topology by applying a displacement map to the base mesh.
