Towards a unified, interoperable real-time 3D asset and beyond

As the chimera of a unified space slowly, but surely, takes shape, it's important to highlight these new formats that are paving the way for a virtualized Internet between spatial computing, the virtual world and extended reality.

While some of these words sound like marketing accorhe exploited by some, others are being analyzed by others.

What does it really mean?

Think of it as a language that everyone can understand, and in which the sharing of information is understood by every system, allowing each platform or tool to be exploited for specific functionalities, but never limited in the way it can be modified or optimized, because there's no longer a limit to the type of file.

This also offers a new way of distributing these formats across the multiple new means of digital expression, with the concrete examples of AR or VR in mind, but all of which can also, for example, be implemented in an NFT and then shared between 2 worlds, one developed on unity and the other on the unreal engine, for example.


Let's go into more detail:

Universal Scene Description (USD): Unifying the Digital Universe

In the vast realm of digital technologies, USD acts as a gravitational force, centralizing data representation for seamless collaboration across departments and applications. Its modular design eases integration of new technologies, making VFX pipelines adaptable and efficient​​.
