AI Technical Summary
Technical Problem
When generating a virtual screen in a 3D scene, existing technologies require users to manually click four points to determine the plane and adjust parameters, which is costly.
Method used
By acquiring the position information and normal vector of the click operation, the preset direction vector of the virtual screen is determined using the camera parameters of the virtual camera, and the virtual screen is generated in the 3D scene based on the planar boundary point data.
Benefits of technology
It reduces operating costs, improves the efficiency and accuracy of generating virtual screens, and enhances user immersion and the interactivity of 3D scenes.

Abstract
The application relates to a virtual screen generation method and device; the method comprises the following steps: in response to a click operation on a three-dimensional scene, acquiring position information of the click operation; using a normal vector in the position information and camera parameters of a virtual camera to determine a preset direction vector corresponding to a virtual screen; obtaining plane boundary point data of the virtual screen according to the preset direction vector, the camera parameters and coordinate data in the position information; and then generating the virtual screen at a corresponding position in the three-dimensional scene; the method can quickly generate the virtual screen in the three-dimensional scene by only performing the click operation, and operation cost is reduced.
