In order to facilitate understanding of the above-described aspects of the present invention, the above-described aspects of the present invention will be described in detail below.
The optimization of the three-dimensional model is almost a work which is required in the development process of each three-dimensional product, and the three-dimensional model is optimized by reducing the number of the three-dimensional models, reducing the quality of the models, controlling the display mode and the like, so that the final effect of the three-dimensional product is smooth, and the experience is improved. However, the optimization tends to have certain limitations, and the numbers are taken as examples: for example, the model scale can be optimized from 100 to 80, and is almost impossible if one wants to optimize from 100 to 10 or even 1. The invention solves the problem, and uses the characteristics of the three-dimensional model of the pipeline classUnity3dThe replication function of (2) redrawing the whole set of three-dimensional model of the pipeline, combiningUnity3dThe model combination method can fundamentally reduce the volume of the three-dimensional model and enable the three-dimensional model to regenerate, thereby greatly reducing the volume of the product, improving the quality and the fluency of the product and realizing the optimization from 100 to 10 or even 1.
In a particular embodiment of the invention, in particular use, a base according to the inventionUnity3dThe method for optimizing the three-dimensional model of the pipeline class comprises the following processes:
the method is characterized in that the pipeline models are mostly cylinders, different places of the pipeline models are extracted, and the same places are finished by a copying method, so that the three-dimensional models are drawn, the whole set of three-dimensional models is optimized, and the following description is given by taking the three-dimensional software product for optimizing a set of thermal power plant display boiler pipelines as an example:
first, the boiler system of a thermal power plant is composed of about 3.5 ten thousand pipelines.
In the first step, the parameters of each pipeline are extracted. The parameters include: position coordinate, name, length, width and direction, and writing them inExcelIn the table, each row of the table is information of one pipe. Because the data volume is large, for the convenience of management, the data volume can be divided into a plurality of files, and about 5000 pieces of information of the pipeline are one file, so about 18 pieces of information are neededExcelFiles to store all the pipe information.
The purpose of this step is to extract the different characteristics of each pipe.
Second, the original three-dimensional model is prepared. In thatUnity3dThe software adds a cylinder model and a sphere model, and all the pipelines of the whole set of boiler system are drawn by continuous copying based on the two files.
And thirdly, drawing a pipeline model. Use ofUnity3dReady for reading of softwareExcelAnd the file is used for copying the cylindrical model, modifying the parameters of the copied cylindrical model according to the information of each line in the file, and modifying the information of the pipeline position, the pipeline name, the pipeline length, the pipeline width and the pipeline direction one by one. At the turn or end of the pipe, the sphere model is copied out as the weld crater of the turn of the pipe. Repeating the steps, and drawing the pipelines of the whole system.
In this step, the use of three-dimensional modeling software to draw all pipeline models is avoided, and the three-dimensional models are drawn in a copying mode instead, so that the time can be saved, and the memory volume of the models can be reduced.
And fourthly, adding a collision body to the pipeline model. A collision body is arranged atUnity3dAre called in softwareColliderIt is used for monitoring mouse click. The whole set of pipeline three-dimensional model is copied, a collision body is added to the cylinder model, and then model information of the cylinder model is deleted, so that the cylinder model is not a three-dimensional model file any more, but a collision body file only.
The purpose of this step is to make each pipeline model support the click function of the mouse, and better satisfy the use of software products.
And fifthly, combining the pipeline models. According to the foregoingExcelGrouping of files, useUnity3dA method of merging models is provided that merges the pipeline models of each group into a large three-dimensional model. That is, as mentioned above, about 5000 tubes are combined into one large three-dimensional model, and 3.5 million tubes of the entire boiler system are composed of about 18 large three-dimensional models.
The purpose of the step is to utilize the characteristics of computer batch processing, pack and compress a plurality of small files into a plurality of compressed packets in a manner similar to the compressed packets, so that the loading and the use are faster.
Through the operation, the 3.5 ten thousand boiler pipelines can be displayed and completed only by more than ten large three-dimensional models, the memory volume and the rendering speed are greatly improved compared with the prior art, and finally, the actual measurement is carried out, and the memory volume of the 3.5 ten thousand pipeline dimensional models is only the memory volume25MBAnd the opening can be completed within 10 seconds and the process is operated.
Through a series of operations, the work of extracting, redrawing, adding collision bodies and combining the information of all three-position pipeline models is completed, the volume of model files can be greatly reduced, the rendering and loading speed is increased, the information of a certain pipeline can be checked by clicking with a mouse, and the normal use is met. Meanwhile, the development time cost is greatly saved, the working efficiency is improved, and multiple purposes are achieved.
In one embodiment of the invention, the thermal power plant boiler wear-resistant and explosion-proof system comprises: with the development and popularization of three-dimensional visualization technology, the application of the three-dimensional visualization technology in the shop industry is more and more. The anti-abrasion and anti-explosion system of the boiler of the thermal power plant is a three-dimensional system commonly used in the thermal power plant, and aims to solve the problems of too many pipelines, difficult searching and difficult maintenance of a boiler room of the thermal power plant, the whole boiler system is modeled in a three-dimensional mode and displayed integrally, so that the anti-abrasion and anti-explosion system can be used by workers greatly, the working efficiency is improved, and the personal safety of the workers is also guaranteed. By applying the invention, tens of thousands of boiler pipelines can be displayed in a three-dimensional product, can be checked at will and clicked at will, the power consumption of rendering and loading is low, a commonly configured computer can be started, the requirement on the network speed is not high, the checking at any time and any place is realized, the dilemma that the watching can be realized only by using a high-distribution computer and a light-speed broadband network in the prior art is broken, and the invention makes positive contribution to the safe operation and maintenance production of a thermal power plant.
In summary, according to the technical scheme of the invention, the method does not need to install a plug-in unit and is simple to use; the development and use efficiency of the channel type three-dimensional products is greatly improved; the time cost is reduced; the memory volume of the model is reduced; the number of models is reduced; the consumption is reduced; the problem that the interior of the industry is generally puzzled is solved.
