A very short post in the sequel of my previous post "Advanced HLSL using closures and function pointers", there is again a little neat trick by using the "class" keyword in HLSL: It is possible to use a class to regroup a set of parameters (shader resources as well as constant buffers) and their associate methods, into what is called a compound parameter. This feature of the language is absolutely not documented, I discovered the name "compound parameter" while trying to hack this technique, as the HLSL compiler was complaining about a restriction about this "compound parameter". So at least, It seems to be implemented up to the point that it is quite usable. Let's see how we can use this...
