Level of detail for terrain geometry images


We consider the rendering of geometry images obtained by parameterization of terrain geometry. This technique reduces texture warping in areas of steep gradient. The selected terrain representation allows terrain that cannot be represented by a heightfield to be rendered. Finally, we demonstrate that the slightly irregular sampling can be rendered efficiently using modern graphics hardware. We introduce an efficient level of detail algorithm that can be applied to terrain geometry images or regular terrain.
