Embodiment Construction
[0040] A method and device for disassembling and assembling a three-dimensional model based on a virtual group object according to the present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0041] In order to solve the problem that the synchronous movement of multiple sub-models cannot be controlled during the disassembly process of the 3D model, and the assembly of two independent sub-objects of the model cannot be controlled during the assembly process of the 3D model, so as to realize the disassembly and assembly process of complex equipment and improve the authenticity of the disassembly process. , the present invention proposes a method for disassembling and assembling a three-dimensional model based on a virtual group object. like figure 1 As shown, the three-dimensional model disassembly method specifically includes:
[0042] Step 1) Complete the preliminary three-dimensional model in the three-dimensional mod...

The invention provides a three-dimensional model dismounting method and device based on a virtual group object. A three-dimensional model manufacture tool is used for manufacturing a three-dimensional model and a dismounting animation, a dismounting flow resource bundle is derived, the three-dimensional virtual dismounting operation and the three-dimensional virtual mounting operation of the dismounting flow resource bundle are executed in a relevant device, and meanwhile, a virtual object group way is adopted to carry out expansion to realize the dismounting and mounting process of the three-dimensional model. The problems that a three-dimensional model dismounting process can not control a plurality of submodels to synchronously move and a three-dimensional model mounting process can not control two independent child objects are solved so as to realize the three-dimensional virtual dismounting and mounting operation of complex equipment and improve the authenticity of the dismounting process.
Description
technical field [0001] The invention relates to the field of three-dimensional virtual simulation, in particular to a method and device for disassembling and assembling a three-dimensional model based on virtual group objects. Background technique [0002] In the training of the use of the product, the demonstration of the structure and principle of the product, the introduction of the operation process, and the introduction of the fault diagnosis process are the contents that are mainly taught to the operator. 3D virtual simulation technology provides a vivid, realistic and intuitive display method for product use training, which can improve the learning efficiency and initiative of operators and maintainers. [0003] For product usage training, when using 3D virtual presentation, an important aspect is how to interact with the operator. This interaction includes the user's operation of the model in the 3D scene, the control operation of the technological process, the cont...
