On December 21, the first domestic meta universe product "xirang" released by Baidu officially opened the directional internal test. Southern + reporters entered the "Greek soil" space in the first batch through the invitation code to open the "first experience" of the meta universe.
After simply establishing the identity ID, the reporter entered the first city in the Greek land world - creator city. According to Baidu, the design concept of Greek soil world comes from a magical topology - Mobius ring, which aims to unify the positive and negative aspects of opposition, break through the impossible, connect reality and virtual, and connect modern and future.
Here, users can have a direct conversation with their partners in all corners of Creator city and listen to the chat conversations of participants within 5 meters. With the change of user location, they will also hear new chat content.
By sliding the "steering wheel", users can also control virtual characters to run at will, and navigate to various virtual buildings built by Baidu in the city, such as Xitu Conference Center, radish express driverless experience station, baidu cloud diving hall, etc., as well as cultural spaces such as Communication University of China, Sanxingdui digital site, Fengtang Art Center, etc.
For example, the Xirang Conference Center, which the reporter entered, is 1600 meters high and has eight doors facing eight directions. It is intended to welcome visitors from eight sides. The tower body is spirally intertwined by eight ties, which means to unite eight sides. It is reported that it can accommodate 100000 users for online meetings at the same time. Participants can feel the effect of being in the middle of a 10000 person venue through live mixing technology. Baidu create 2021 (AI Developer Conference) to be held on December 27 will also be held here.
It is understood that this will also be China's first large-scale conference held in the "meta universe".
However, in the "meta universe" world, a large number of data transmission and calculation are carried out all the time. How to realize the interaction of 100000 people on the same screen, "10000 concert" real sound effect and immersive interactive experience has become a barrier at the door of Baidu's technical team.
According to Ma Jie, vice president of Baidu, yuanuniverse development faces three "technological mountains" of vision, hearing and interaction. To build a stable and safe "meta universe" world, we not only need to break through a series of technical bottlenecks, but also need the support of strong basic technical capabilities. These key technologies include: secure, autonomous and intelligent cloud computing technology; Continuous innovation in artificial intelligence, arm cloud, edge computing, intelligent video, VR and AR; The construction of content ecology and huge market foundation.
To this end, Baidu brain has increased R & D investment in the field of vision, speech and natural language understanding, and has greatly improved Baidu's computing power through efforts. In addition, with the help of "Ai native cloud", baidu provides the Greek earth world with PFlops level super heterogeneous computing power, hundreds of GB bandwidth resources and infinitely scalable storage.
"After more than a year of development and testing, the version number of xirang is still a negative number, there are still many imperfections, and it still has a huge growth space from our envisaged goal." Ma Jie said, "at present, the meta universe is still in a very early stage of industrial exploration. Its development is gradual and will take a long time for the whole community to build and mature together."
