Problems solved by technology

[0004] At present, although some local and cloud software have achieved partial parameterization capabilities, the common parameterization software on the market is very complicated and difficult to set the size, and does not combine the current commonly used modeling behaviors, resulting in modeling efficiency. relatively low

Embodiment 1

[0026] A regular grammar based on variable parameter space division, including grammar definition and grammar analysis,

[0027] Step 1. The user fills in the sentence according to the grammar, where the specific writing method of the grammar is:

[0028] A node is identified between two ":";

[0029] Take the basic node as the unit, and the basic node supports multiplication and division;

[0030] Each basic node can be combined into a combined node through "+" and "-";

[0031] Use "[]" to identify multiples that express exact values, such as [32mm]. The multiplication and division of "[]" can be placed before and after, such as 2*2[32mm], can express 4[32mm], 2[32mm]*2 can also express 4[32mm];

[0032] "[]" can also fill in the parameters set by the system, and "[]" can also analyze the parameter results;

[0033] n*"{}" can be used to express that a repeated node is copied n times;

[0034] When there is no relative node in the combination node, the exact value node ...

Abstract

The invention discloses a variable parameter-based space division rule grammar, which comprises grammar definition and grammar analysis. The grammar definition is used for setting accurate numerical value nodes: the grammar definition has no mutual influence relationship with other nodes and determines the length of the grammar definition; the relative node is provided with a proportion part, andthe length except the accurate node is allocated with other relative nodes in proportion; and the multiple of the accurate numerical value is obtained, that is to say, after proportional calculation,the system calculates a value which is smaller than the total length of the segment and is the multiple of the accurate numerical value. The variable parameter-based space division rule grammar can beachieved, a user does not need to set complex parameters, parameterized segmentation and expression can be rapidly carried out on areas and spaces according to a grammar mode set by a system, the starting difficulty of the user is reduced, and the modeling efficiency is improved.

Description

Technical field: [0001] The invention relates to the field of home decoration, in particular to a rule grammar for space division based on variable parameters. Background technique: [0002] Parametric modeling is a computer-aided design method and an important process of parametric design. Through parametric modeling tools, a parametric model of a real-world object is constructed. The parametric model is not only consistent with the three-dimensional appearance of the real-world object, but also has a complete information base consistent with the actual object. This information base enables parametric models to be used not only in design, but also in other parts of the supply chain such as model production and transportation. For the panel home furnishing industry, the parameters are often not fixed, but change within a certain range, so that one model can be used for multiple purposes, and the efficiency of design, modeling and other links can be improved. [0003] The c...
