This application discloses a three-dimensional data obtaining method and a related apparatus, and relates to the field of internet technologies. The method includes: receiving a data obtaining request sent by a user terminal, where the data obtaining request carries a target uniform resource locator URL and three-dimensional indication information, the target URL is a URL of target virtual space, and the three-dimensional indication information indicates a target three-dimensional model in the target virtual space; obtaining data of the target three-dimensional model based on the target URL and the three-dimensional indication information; and sending the data of the target three-dimensional model to the user terminal. In this application, three-dimensional data is sent to the user terminal via a content delivery network, so that a three-dimensional data delivery speed can be improved.
