Unless I'm wrong, in my understanding what the and the "end" integrators such as directlight are doing is similar to the following example I just wrote:

Code: Select all
#include <iostream>

class class1
        virtual void printNameChild() = 0;
        void printName()

class class1child: public class1
        virtual void printNameChild() { std::cout << "This class is class1child" << std::endl; }

int main()
    class1 * object = new class1child;
    return 0;

If you compile this with:
Code: Select all
g++ -o inheritance

when you execute it you should get this message:
This class is class1child

As you can see in this example, within the class1 printName() member function I'm calling printNameChild() without specifying an object. In fact, this originates from class1child who executes it's parent printName() function (not redefined in the child) which in turn executes the child printNameChild() function.

I hope this helps. I could be wrong, of course but this is how I understand it.

This helped a lot. Quite a puzzle. I guess, in C it would've been implemented something like

Code: Select all
switch (integrator)

{   case directLighting: ...

    case photonMapping: ..., etc.

Probably, would've been easier on the brain.
