Contents

This lecture deals with the fundamentals of photorealistic and interactive image synthesis. In particular, we discuss techniques to achieve interactive frame rates for the realistic rendering of complex models and scenes. Selected graphics algorithms and their efficient implementation exploiting state-of-the-art graphics hardware through OpenGL will be demonstrated. We focus on dedicated parts of the graphics pipeline and we review the functionality provided by consumer class graphics accelerators including programmable vertex and fragment units. In addition, we discuss the governing equations in physics based light transport and we demonstrate effective solution methods for the simulation of global illumination.
