1. A data transmission method, being applied to a server side and comprising:
receiving current status information sent by a client;
determining, according to the current status information, status-dependent point cloud spatial region information corresponding to the current status information;
selecting status-dependent point cloud spatial region data corresponding to the status-dependent point cloud spatial region information; and
sending the status-dependent point cloud spatial region information and the status-dependent point cloud spatial region data to the client;
wherein determining, according to the current status information, the status-dependent point cloud spatial region information corresponding to the current status information comprises one of the following:
selecting a point cloud region with a preset shape according to the current status information, and determining information about the selected point cloud region as the status-dependent point cloud spatial region information;
determining a position of a next movement status of a user using the client and an orientation of the next movement status according to current position information of the user, current orientation information of the user and movement information of the user which are included in the current status information, and determining point cloud spatial region information corresponding to the position and the orientation as the status-dependent point cloud spatial region information; or
determining a spatial region touched by a hand of a user using the client according to a hand position of the user and a hand motion of the user which are included in the current status information, and using information about the spatial region touched by the hand as the status-dependent point cloud spatial region information.
