Description

IPDE-based ship product three-dimensional model data visualization construction method

Technical Field

The invention relates to a ship design technology, in particular to a ship product three-dimensional model data visualization construction method based on IPDE.

Background

The general design of a ship is a project which involves a lot of personnel and complex product information, and in the process of developing ship products, each professional needs to browse a three-dimensional model of the ship product by means of third-party three-dimensional design modeling software (such as Foran and Catia), but the method not only needs to master a certain software use basis, but also seriously reduces the working efficiency.

Therefore, in order to improve the working efficiency of the cooperation of professionals in ship design and achieve the purpose that the professionals in ships can manage data and browse a three-dimensional model on line in an integrated product data environment (hereinafter, abbreviated as "IPDE"), a general method for visually constructing three-dimensional model data of a ship product is needed.

Disclosure of Invention

The invention aims to solve the technical problem of providing a ship product three-dimensional model data visualization construction method based on IPDE (IPDE-based extension) aiming at the defects in the prior art.

The technical scheme adopted by the invention for solving the technical problems is as follows: an IPDE-based ship product three-dimensional model data visualization construction method comprises the following steps:

step 1, newly building a Domain in a model structure tree of an Integrated Product Data Environment (IPDE); the three-dimensional model of the ship product comprises a model, a component, equipment, a region and a system;

step 2, newly building a three-dimensional model Zone of the ship product under Domain;

step 3, generating a script file after the three-dimensional model Zone is completed through the step 2, and releasing the script file, wherein the server side can automatically generate a corresponding data table;

step 4, designing and developing a client application of the Zone based on the IPDE, and introducing a visual plug-in into the application;

step 5, importing the attribute data and the three-dimensional model data of the Zone into the data table generated in the step 3;

step 4 and step 5 can be executed in parallel;

step 6, the client application developed in the step 4 and the attribute data imported in the step 5 are managed in an associated mode;

step 7, converting the model data imported in the Step 5 into a standard three-dimensional geometric format Step format at the server;

step 8, converting the Step format obtained in the Step 7 into a lightweight format including ivp and iva formats, and generating an interface URL;

step 9, calling the URL in the step 8 through the visual plug-in the step 4 to realize online browsing of the three-dimensional model, and completing data visual construction of the three-dimensional model Zone of the ship product;

and 10, sequentially completing data visualization construction of the model, the component, the equipment and the system in the three-dimensional model of the ship product according to the methods from the step 2 to the step 9.

The invention has the following beneficial effects:

the method solves the problem that professionals in the overall design process of the ship can not browse the three-dimensional model directly and need to use third-party three-dimensional design software such as Foran, Catia and the like, so that the professionals can manage data and browse the three-dimensional model on line in the IPDE, and the working efficiency is greatly improved.
