What is AES

On the basis of real physical elements, 51Aes (All Element Scene) is able to faithfully simulate 3D scenes with computer graphics and artificial intelligence, to realize real-time rendering of ultra-large-scale scenes and individualized management of all elements.

How to build AESs

51Aes can quickly convert various model files describing the real physical world into virtual scenes of the digital twin world. Relying on computer graphics, computer vision, big data, cloud computing and other technologies, AES can automatically or semi-automatically construct a digital twin world.
