Abstract: The present application provides a double-beam laser polishing device and a double-beam laser polishing method for an aluminum alloy, which includes a frame; a rotary workbench and an optical path system, which are arranged on the frame. The optical path system includes: a first fiber laser, a second fiber laser, a first three-dimensional galvanometer, and a second three-dimensional galvanometer. The first three-dimensional galvanometer is connected with the first fiber laser through an optical fiber, and the second three-dimensional galvanometer is connected with the second fiber laser through an optical fiber. The first three-dimensional galvanometer and the second three-dimensional galvanometer are arranged side by side above the rotary workbench in a horizontal direction.

Abstract: The present application discloses a VR scene and an interaction method thereof, and a computer-readable storage medium. The method includes: constructing a semantics path, here the semantics path is a trajectory drawn on geometry of the virtual environment agent and composed of nodes and directed connections among the nodes, and information of the nodes includes at least node position information, node behavior semantics information and node environment semantics information; the semantics path, moving the virtual character agent according to its own task and the semantics path, and executing a target action; acquiring action result information according to information of a target action of the virtual character agent at the node of the semantics path, and instructing the semantics path processing unit to update the node environment semantics information of the node of the semantics path. Embodiments of the present application can effectively realize interaction in the VR scene.

Abstract: This application discloses a target tracking method and apparatus, a terminal device, and a storage medium. The target tracking method includes: determining a path node nearest to the virtual character as a travelling node according to a starting position of the virtual character; moving toward the travelling node until arriving at the travelling node; determining a current next path node to be reached by the virtual character according to the path node where the virtual character is currently located, the path node currently nearest to a target being tracked and a pre-stored path routing matrix, here the path routing matrix is a matrix storing an optimal next path node from a first path node to a second path node; moving to the next path node to approach the target being tracked. Embodiments of this application can improve the target tracking efficiency of the virtual character in the VR scene.
