Real-Time Relighting of Compressed Panoramas |
Abstract: Surface patches are a memory-efficient way of creating smooth surfaces that can be rendered at many levels of detail. However, having a smooth surface is not as useful if you cannot light it properly. For that, you need the normal vector at each vertex. This article describes how to treat the normal at each control point as a second control mesh, thus quickly approximating the correct surface normal. Although the results are not strictly correct, they can produce superior results by eliminating shading errors due to curve discontinuity introduced during skinning.
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.
Cube Map Lighting Techniques |
Abstract: This article will describe some ways to encode different lighting conditions as well as other properties within cube maps. It will give a brief overview of the properties of cube maps and how to index into them. Topics include: Physical Properties of Cube Maps, Getting data to/from a Cube Map, Rendering with the Cube Map, Encoding Cloud Cover, Encoding Lights in a Cube Map, Encoding Diffuse Lighting in a Cube Map, and Encoding a Day/Night Cycle into a Cube Map.
Textures as Lookup Tables for Per-Pixel Lighting Computations |
Abstract: In this article, we show ways to use texture maps as a means to solve functions through a lookup table, focusing on lighting computations. This technique saves precious pixel shader instructions, and in many cases, it is the only way to make certain per-pixel effects possible on the current generation of hardware.

Dynamic Per-Pixel Lighting Techniques |
Abstract: This article presents several techniques that can be used to perform dynamic lighting effects on a per-pixel basis. These methods have the advantage that they don't require highly tessellated geometry, and can often be performed at little performance cost on multitexturing graphics hardware.
