Abstract
In some embodiments, a method for high-performance terrain rendering may include one or more of the following steps: (a) obtaining elevation data, (b) determining slope of a terrain surface, (c) selecting a shading model to apply to the terrain surface based upon the slope of the terrain surface, (d) determining if a vehicle's heading has changed, and (e) aligning the shading model index based upon current heading.
