There are several stochastic vol models, what I'm studying is Heston. What the paper (written by Heston) studies is European options, but nowadays the popular use of stochastic vol models is to price exotic options, where can I find more information ? Say, an example to price an exotic option with a stochastic vol model. I mean, I don't know where I can get related resources (application of stochastic vol models on options other than European options)
