Load 3D models at run time from a PlayCanvas application

Hi, everybody.

I am new to PlayCanvas, although I have a great deal of experience with other 3D engines and libraries (Unity, OSG, …).

I would like to know what I should do to load a 3D model AT RUNTIME (this is the key of the question) from an application developed over PlayCanvas.

In Unity it can be done with OBJ files. In OSG, it can be done with several 3D file types.

I have read somewhere that PlayCanvas can load models at runtime using a JSON format (specific for PlayCanvas), but I have been unable to make it in a few sample projects that I have tested.

Is it true that models can be loaded at runtime within a PlayCanvas application?
If so, how?
It is possible to load at runtime an FBX model, for instance?

Thanks in advance.
