Figure 1: Rendering of the Como Lake (4096×4096 heightfield) using our method combining mesh rendering and ray-casting. This frame
is rendered at 43 Hz on a viewport of 1900 × 700 px. The right part of the figure depicts the division of the terrain amongst the mesh and
ray-casting with its four levels-of-precision.
ABSTRACT
This paper presents a flexible hybrid method designed to render
heightfield data, such as terrains, on GPU. It combines two tradi-
tional techniques, namely mesh-based rendering and per-pixel ray-
casting. A heuristic is proposed to dynamically choose between
these two techniques. To balance rendering performance against
