Using impressionist painter Vincent van Gogh's "Al Night's Open Cafe", "Night Cafe" and "Starry Moon Night" as materials, combined with 3D modeling software MAYA and creation platform Unity, the virtual visualization of painting is realized and a decryption game with the theme of "Van Gogh World" is created. Players can roam the scene and interact with the items from a first-person perspective to experience game decryption.
