Virtual reality is about an other reality. Not like the actual reality that surround you.
Virtual reality is close to the scope of entertainment because it can display any reality even the fixtuous ones. Out goes from the realty displays in game. Level game. For games. Even gtav. We can imagine how the actual movie industry could use vR to display a new kind of movie
Augmented reality is about modifying our reality. The current works we live in. It is a way more profound change.
AR is more about utilities. VR is more about entertainment
Just trying to better understand the meaning of those words. Those concepts are very young. Their definitions is still very vague.
How to display it. Where is the screen for the user. Is there a single screens? Or two, one for each eye. Is it see thru display. Is it more normal opaque screen. Can user perceive depth
Relation between screen position and the latency issue to fool the brain
What reality is displayed? What is the type of content. Is it purely v

jsdocFunction

It ensures the jsdoc of your function is respected during execution. Check out the live demo.

API

var newFct = jsdocFunction(yourFct)

The code you see below is a funny building of chained API :) it is a particle emitter for flame throwers. look at the running demo. I love the end of the flame. all in a single chained instruction. Recently i did all my libraries with chained api and i like it. the lib used below is fireworks.js. This particular emitter is a bit too much chained tho :)

but still i look at the size of the source and at the effect on the screen... you got a pretty cool looking effects for 60lines of javascript. maybe i should just break it in several instructions... would be artificial but hey :)
