Rediscovering an older plugin of mine, jMatch3, based on the library of the same name by Cyrille Bogaert sparked the additions made with the recent update of Baby 3D.

Because when I attempted to convert the simple example I made for that plugin to 3D I noticed a few shortcomings. 

Especially the basic act of clicking on a mesh couldn't be easily realized when the perspective in 3D space wasn't lined up well with the original 2D layout view.

While picking via ray is already possible it isn't necessarily ideal for this task.

Fortunately Babylon.js provides functionality to simply pick from canvas coordinates so it just needed proper integration into the plugin. 

You can check the resulting example out for yourself and see how a few of the new things in update 0.89 are applied.

However for this example you do need to have the MoveTo plugin by rexrainbow. And also the aforementioned jMatch3 plugin which I made available again here on the plugin page.
