基于BNF的3DS文件格式规范化描述

摘要

3DStudio(3DS) is a file structure of 3dsMax used to store model information, which is one of the industry's standard format in 3D software. In order to ensure the models of different system can be called freely, to solve the problem that the different model format is not compatible in visual system, and to reduce the storage space of 3DS file, this paper proposes to use the Backus-Naur Form (BNF) specification to describe the 3DS file. This paper describes the characteristics of the BNF and the method of describing and analyzing the 3DS file structure, and takes the 3DS file of Tethys model as an example, using BNF to formally definite it, thus forms a unified format of standardization management, which facilitates retrieval and application of search engine.%3DStudio(3DS)是3dsMax用来保存模型信息的一种文件结构, 是业界的通用标准格式之一. 为了使不同星系之间的模型可以被自由调用, 解决可视化系统中模型格式不兼容的问题, 减小3DS文件的存储空间, 提出使用巴科斯范式(BNF)规范化描述3DS文件. 描述了BNF的特点和对3DS文件结构进行表述和分析的使用方法, 并以土卫三模型的3DS文件为例, 使用BNF对其进行形式化定义, 从而形成了统一的规范化管理格式, 以利于搜索引擎的检索和应用.
