Embodiment Construction

[0013] See attached figure 1 , the present invention adopts "SketchUp" software to set up the "SketchUp" model of each object of interior decoration engineering, then utilizes ruby ​​language plug-in program to calculate the quality and the center of gravity of interior decoration engineering, concrete calculation is carried out by following steps:

[0014] (1) Use the "SketchUp" software to establish the "SketchUp" model of each object in the interior decoration project.

[0015] (2) Read the material and density of each object as a user-defined input item, and assign it to the attribute item of the model entity corresponding to the object with the same material in "SkechUp".

[0016] The reading and assignment are realized by calling the "get_attribute" and "set_attribute" functions of SketchUp ruby.

[0017] (3) Calculate the number of faces of the "SketchUp" model of each object in the interior engineering, the number of vertices and the coordinates of vertices of each fa...

Abstract

The invention discloses an algorithm for mass and gravity center of ship cabin interior decoration engineering. The algorithm is characterized by establishing a SketchUp model for each object of the interior decoration engineering by adopting SketchUp software, then, calculating the mass and gravity center of each object of the interior decoration engineering by using a ruby language plug-in program, and then, outputting and creating a table file by a user interface of the SketchUp or file access of the SketchUp so as to display calculated results of the mass and gravity center of each object of the interior decoration engineering. Compared with the prior art, the algorithm has the advantages that the calculation is convenient and fast, the accuracy is good, the hydrodynamic force and navigation safety performance of a ship are effectively improved, particularly, the calculation process is simplified, the design quantity of the engineering is reduced, the working efficiency is greatly increased, and the algorithm is particularly applicable to the calculation of the mass and gravity center of a material of a complicated space structure, can be used for solving the mass and gravity center of any entity model in the SketchUp and is convenient in calculation and high in accuracy.

Description

technical field [0001] The invention relates to the interior engineering design of ship cabins, in particular to an algorithm for material quality and center of gravity of ship cabin interior engineering based on "SketchUp" design software and "ruby" programming. Background technique [0002] At present, in the interior engineering design of ship cabins, the mass and center of gravity calculation of its decorative engineering materials generally use engineering drawings drawn by two-dimensional CAD software, and then calculate the volume, density and coordinates of materials manually. The calculation workload is very large, and it is difficult to accurately calculate the material mass and center of gravity of complex spatial structures. Conventional calculation methods are not only inefficient, time-consuming and labor-intensive, but also the accuracy cannot be guaranteed, seriously affecting the hydrodynamic performance of ships, and even endangering navigation safety.
