What is the meta universe ?
Many people think of the version of the metauniverse as a movie 《 No. 1 player 》 Oasis of , The primary version mostly refers to the meta universe Roblox—— An open game production and distribution platform . Of course , If you really get into the game, try , You will find Roblox There is still a long way to go from the number one player , Under the condition that the existing technical infrastructure is not perfect , To balance development difficulty and immersion ,Roblox At present, only pixel level game experience can be given , For gamers who are used to big production, it may not be fun enough .
The universe must be more than games , It's not necessarily the appearance of the number one player . There is still a distance between such a meta universe and reality , There is no real connection and interaction between production and life in the real world , And bring more profound revolution and value . These two days SIGGRAPH2021 The conference played back a section of NVIDIA Huang Renxun “ The setup ” In the video , Once again Nvidia Omniverse The platform is displayed in people's vision . NVIDIA is based on Omniverse The proposed concept of meta universe shortens the distance between illusion and reality , Take people's imagination of the meta universe into reality .
The system structure of the meta universe
First , The metauniverse must be built on advanced digital infrastructure . Primordial “ immersion ”“ Low delay ”“ Anywhere ” Characteristics not only for VR/AR Hardware technology and network transmission system put forward high requirements , It also depends on high-performance cloud computing power and streaming media technology . AI can accelerate the production and distribution of content , Enrich the content and ecology of the meta universe . Blockchain supports the effective operation of the economic system , While ensuring the security of digital assets and digital identity , Realize the value exchange of digital products and ensure the transparent implementation of system rules .
On top of digital infrastructure , Three dimensional digital content development system and economic system are the core power engines driving the operation of the meta universe . Based on the former , People can continuously input rich information into the field of consumption and production in the meta universe 、 Diversified digital assets / product , Expand the reach boundary of the metauniverse . Based on the latter , Digital currency 、 Financial instruments and trading markets can further activate and promote the consumption of digital content and its value spillover to the production field .
secondly , Security 、 Rules and civilization ensure that there is a bottom line for the operation of the meta universe 、 Orderly 、 sustainable . Safety is the bottom line , It includes both individual privacy and security 、 Institutions / Organization's data security 、 Network security, etc , It also includes whether the digital content itself involves violations 、 Unconstitutional , And the security protection of digital assets . One side , These security issues need regulation and administrative supervision ; On the other hand , For mass 、 The generation and iteration of highly concurrent digital content need to be solved by technology , Artificial intelligence will play a major role . With good rules and constraints , The universe can develop orderly , And a new digital civilization in line with human values , And the matching allocation pattern 、 Virtual civil rights will jointly promote the sustainable development of the meta universe .
Yuanyu's content development system
As one of the core power engines , The content development system of metauniverse mainly includes the basic layer 、 Platform layer and tool layer .
Base layer (IaaS layer ) It mainly provides computing power and data storage support for content development . for example , Ying Wei Da RTX The server guarantees the computing power in terms of hardware ( Especially for AI Calculation 、 High quality rendering, etc ), And provide desktop to cloud computing solutions for development organizations of different sizes and use needs .
Platform level (PaaS layer ) It is the core component of the content development system , Including technology engine and data platform , It can also be regarded as the middle stage of the ability to support digital content development . We are familiar with the game development engine Unity,UE Have strong ability in game content development ecology .
The technology engine part includes various technical capabilities to realize the reality of the virtual world , For example, materials & Rendering 、 physical mechanics 、 Audio effects 、 Digital people, etc ; Virtual reality interaction engine to realize the intellectualization of hybrid reality ; Cross platform multi person real-time online operation 、 Artificial intelligence and other general technology stacks .
In the data platform , By opening the external data interface, various modal data can be imported for processing ( Including 3D reconstruction of point cloud data ), And then fuse to form material resources with depth information , It is convenient for unified management and calling at any time , It also prepares materials for further rendering and interaction .
Tool layer (SaaS layer ) Mainly for a wider range of developers , It does further low code processing for platform capabilities , And provide a set of low threshold content development tools and micro components . Generally speaking , In order to facilitate developers using different platforms , At the same time, for different interactive end users , The tool layer will be multi platform / Terminal adaptation or compatibility , To improve the smoothness and cohesion of the development process .
