Stanford CS348B, Spring 2022
IMAGE SYNTHESIS TECHNIQUES

High-quality rendering is ubiquitous today, with applications ranging from entertainment to product design and architecture. The goal of this course is to provide a deep understanding of the fundamental mathematical and physical principles that are the basis of modern physically based rendering while also introducing the design principles and engineering trade-offs involved in designing and implementing high-performance rendering systems.
