Understanding primary and secondary bounces

As we've already noted, in the real world, light doesn't just bounce once. After being emitted from a source, it will, for all intensive purposes, just keep on bouncing. Not that we are saying it stays infinitely bright, mind you. After an unspecified number of bounces, or after a certain distance traveled, the level of light energy will become so low, that is really is no longer contributing illumination to the environment that can be perceived by the human eye. The energy is still active, of course; the falloff or decay rate of light is such that, mathematically, it can be said to actually never reach absolute zero.

Now, I'm sure you can imagine that performing such an infinitely reducing calculation, in a manner completely true to the laws of physics, tracing every potential light path and bounce, well, that would be extremely expensive; extremely slow in terms of computation required. Thankfully, V-Ray has been designed in such a way so as to give us a very high level of flex...
