Let's continue a prior topic of a simple acronym "FUSE" to describe glTF. 

The first three letters are: F for Fast,  U for Universal, S for Simple. 

The acronym concludes at E, meaning Engaging. 

Of course every glTF is 3D, which invites the audience to interact, to explore, to enjoy the freedom, and to be in control. 

It's assisting a bidirectional dialog, beyond the traditional way of passive information dump.

In addition, look at the visual quality! 

The helmet feels so life-like, realistic and attractive with the textures, reflection, scuffs, lighting, that I feel putting it on and start piloting. 

Here is another site with nice samples. 

The chair feels so real with the leather textures, colors, reflections, just like the one in a daily living room.

In short, glTF provides a much more engaging experience for your audience than traditional media, opening doors for Augmented Reality (AR) and Virtual Reality (VR).

Hope you find it helpful too.
