Explore the fundamentals and advanced techniques of photorealistic rendering through this comprehensive university-level course from TU Wien covering ray tracing and global illumination. Master essential concepts starting with radiometry, light attenuation, and BRDF models before progressing to the rendering equation and various shading techniques including diffuse, specular, and ambient approaches. Learn the mathematical foundations including Fresnel equations, Schlick's approximation, Snell's law, and total internal reflection, then apply these concepts to practical implementations of ray-sphere intersection, surface normals, and shadow rendering. Develop understanding of camera models, recursion principles, and Heckbert's taxonomy while working through hands-on assignments that reinforce theoretical knowledge. Advance to sophisticated global illumination techniques including Monte Carlo integration methods, importance sampling, and path tracing with next event estimation. Discover optimization strategies through space partitioning, tone mapping techniques including Reinhard's tone mapper, and advanced sampling methods using low discrepancy sequences and Russian roulette path termination. Explore cutting-edge rendering algorithms including bidirectional path tracing, multiple importance sampling, Metropolis light transport, and photon mapping techniques. Conclude with advanced topics such as stochastic progressive photon mapping, vertex connection and merging, path space regularization, manifold exploration, and an overview of significant rendering research developments from 2013-2015, providing a complete foundation for understanding modern photorealistic rendering systems.
