Chapter 2 introduces the process of the realistic graphics: situation - model view-change visualthreshold -cut hidden-side eliminating and visible bright-ness calculation, etc.
As filter Banks are used to simulate the contrast sensitivity function (CSF) in these models, the complexity of visualthreshold obtainment and real-time (assessment) algorithms are increased.
