Real-Time Rendering

3   Linear Model Analysis of Real-Time Rendering

3.1   INTRODUCTION

The real-time computer graphics rendering process embodies complex state transitions and fast dynamics amidst observable steady-state behaviour. To yield realistic or visually useful graphical information, the rendering process may be loaded with myriad combinations of the input variables and states to the point where it is important to describe this function in simple terms.

In this chapter, we describe the application of system identification methodology to real-time rendering. The basis for such an approach is that the rendering process may be treated from a system perspective as a data processing function. This allows us to analyse the process input and output data to ...
