Abstract:
Advanced real-time lighting and shading techniques are presented in this thesis. We begin with the per pixel Phong lighting, then explain and implement the bumpy environmental mapping enhanced with a Fresnel term, both with pixel shaders 1.4 and 2.0. After this prelude, advanced lighting models are described. Oren-Nayar lighting is used for rough surfaces such as clay. We implement it with shaders 2.0. Cook- Torrance model is mainly used for shiny metallic surfaces and we show version for pixel shader 1.4 and 2.0. Thesis ends with implementation of soft edged shadows created with the improved shadow mapping technique.
