Modelling Non-Linear Rendering Processes - Real-Time Rendering: Computer Graphics with Control Engineering - page 66

This linearised model representation of the rendering process makes it possible for
a user to design a control system in which the output of this system model can be
driven to produce the stable frame rates required in interactive applications.
4.7 CONCLUSION
This chapter described approaches to modelling the non-linear real-time rendering
process. Since linear models cannot fully capture the characteristics of certain ren-
dering processes and typically cover a larger operating range, we proposed the use of
neural networks and the fuzzy inference system. The application of these techniques
was demonstrated in experiments with various rendering processes. The results indi-
cate that both techniques are capable of producing accurate system models from the
measured data.
