Implementation method of cancel operation in three-dimensional scene design and device thereof

Abstract

The invention provides an implementation method of a cancel operation in a three-dimensional scene design and an implementation device. The method comprises the following steps: designing and defining a 3D (three-dimensional) rendering object base class; designing and defining all 3D rendering object classes, characteristic attribute classes and characteristic attribute linked lists; designing event interfaces; defining a global 3D rendering object linked list; triggering the event interface of the 3D rendering objects when a user modifies the 3D rendering object in a three-dimensional scene; automatically obtaining the characteristic attribute of the 3D rendering objects by the event interfaces, and pressing the obtained characteristic attributes into the characteristic attribute linked list; automatically traversing the 3D rendering object linked list when the user carries out the cancel operation, orderly transferring a cancel operation interface of each 3D rendering object, and finally finishing the cancel operation of the overall three-dimensional scene. According to the implementation method of the cancel operation in the three-dimensional scene design and the implementation device, the complexity of software design is greatly simplified, and the maintainability of software is improved.

Description

technical field [0001] The invention relates to a method for realizing undo operation in software design, in particular to a method for realizing undo operation in three-dimensional scene design and a device for realizing undo operation in three-dimensional scene design. Background technique [0002] Because 3D design can show an application scene or the structure of an object, coupled with the continuous development of 3D design technology, 3D scene design has been more and more widely used. The 3D scene design software will provide various operations in the application, such as adding and deleting various rendering objects in the scene, moving, rotating, and labeling the rendering objects, etc. Just as commonly used software needs to provide undo or back functions, users also need 3D scene design software to provide undo or back functions when actually using 3D scene design software, so that users can quickly restore the 3D scene to a certain historical state.

Problems solved by technology

However, because the traditional method records the user's operation and the corresponding parameters, for different operations of the same 3D rendering object, the parameters required for this operation must be defined and cannot be shared, which is very important for the upgrade and maintenance of 3D scene design software It is very inconvenient; and as the operations provided by the software continue to increase, the design complexity of the software will increase greatly, especially for the 3D scene design software with complex functions, the design complexity of the above software has become a problem that has to be solved
