Double-click or double-tap to go quickly to some distant point
When I double-click some point of the image as a user of a walkthrough, I'd like it to transport me to the nearest point to where I double-clicked.
I mean, similar to when I carefully click on a distant scene center, except it doesn't require that I carefully click the circle, as it detects a "double-click" and uses as actual target the scene center to where I double-clicked.
The point here is: "double-click" action to be different from "click" action, and it makes you move faster in the space (as if you were "running fast" from point to point in the true space). Useful to let users discover easier the more interesting areas in a space, and so spend more time to enjoy them instead of to reach them.
