Fast Heightfield Normal Calculation |
Abstract: Heightfields are two-dimensional arrays of height values, commonly used to store terrain or water surface data, and are also commonly used for calculating bump maps. This article will describe how we can take advantage of the special characteristics of heightfield meshes to significantly optimize vertex normal calculation.
Methods for Dynamic, Photorealistic Terrain Lighting |
Abstract: This article will present several methods for producing high-quality, physically based lighting solutions for terrain under dynamic lighting conditions. Topics include: Sunlight (Horizon Angles, Shadow Ellipses, and PTMs), Skylight (Radiosity Approximations and Patches), Animated Cloud Shadows, Video-Based Solutions, and Nonterrain Objects.

Simplified Terrain Using Interlocking Tiles |
Abstract: This article proposes a simple method for interlocking tiles that requires a minimal amount of coding. The technique offers the benefits of dynamically adapting detail levels and animation flexibility. It does this while maintaining a data system that is perfectly suited for hardware transform and lighting.
