example 1

[0140] This example provides a method of rotating a moving object to keep the posture of an object (hereinafter collectively referred to as the object to be rotated) unchanged in 3D space and turn to another object (hereinafter collectively referred to as the target object, corresponding to the aforementioned second object) , regardless of whether the orientation vectors of the rotated object and the target object are in the same plane. For example, if there is a rotated object in 3D space, the vertical x-z plane stands facing the negative direction of the z-axis, and there is a target object above the right front.

[0141] The method provided in this example can keep the standing posture unchanged while the object being rotated turns to the target object, that is, the vertical x-z plane standing posture remains unchanged, without tilting due to turning.

[0142] When the object being rotated is turned under the existing method, it is easy to tilt during the rotation process, ...

Abstract

The embodiment of the present application discloses a method and device for rotating a moving object, a control device, and a storage medium. The method for rotating an object includes: projecting a first object onto a target plane to obtain a first projection; obtaining a first vector based on the first projection and target orientation; projecting the orientation vector of the first object onto the A target plane to obtain a second vector; based on the first vector and the second vector, control the rotation of the first object along a target axis perpendicular to the target plane.

Description

technical field [0001] The present application relates to a method for rotating a moving object, and in particular to a method and device for rotating a moving object, a control device, and a storage medium. Background technique [0002] In some three-dimensional (Three dimensional, 3D) image scenes, rotating a controlled object, in addition to changing the orientation of the controlled object, will make the controlled object tilt relative to the plane on which it stands and other unnecessary gestures Changes, so that the control of the controlled object in this 3D scene has errors or low precision. Contents of the invention [0003] In view of this, the embodiments of the present application are expected to provide a method and device for rotating a moving object, a control device, and a storage medium. [0004] The technical scheme of the present application is realized like this: [0005] The first aspect of the embodiment of the present application provides a method ...
