Texture filtering is an important implementation detail of every rendering system. Its purpose is to achieve high-quality rendering of textured surfaces, while avoiding artifacts, such as aliasing, Moire patterns, and unnecessary overblur. In this chapter, we extend the ray cone method for texture level of detail so that it also can handle refraction. Our method is suitable for current game engines and further bridges the gap between offline rendering and real-time ray tracing.
