I have developed a model of roughness of my own, and I have been reportin= g information about this in some papers. I am currently working on a came= ra ready paper for the international puredata convention (yes, my model w= as implemented in puredata) that will take place at MC GILL Canada (21st-= 26th Aug)! Who from the list might I meet there? I will definately talk a= bout this! Pressnitzer also has a model in puredata, please let me know about all th= e models you have encountered so far. According to Vassilakis, though, Pr= essnitzer's model has some failures. Anyway, I do review most of the roughness models in my work, and so does = Vassilakis on his thesis. He has a nice chapter on roughness model drawba= cks, but I do have some remarks to add to his work, and I have actually b= een telling him about it... Another paper that I am working on right now also discusses the modelling= , but this one is in portuguese, anyway, I will translate it to english a= nd post it on my website too... Please, tell me more about your research, I will be glad to participate.
