1. 项目的目录结构及介绍

gltf-pipeline 项目的目录结构如下：

gltf-pipeline/
├── bin/
│   └── gltf-pipeline.js
├── lib/
│   ├── gltfPipeline.js
│   ├── processGltf.js
│   ├── glbToGltf.js
│   ├── gltfToGlb.js
│   └── ...
├── test/
│   ├── spec/
│   └── ...
├── doc/
├── package.json
└── README.md

目录介绍：

• bin/: 包含命令行工具的入口文件 gltf-pipeline.js。
• lib/: 包含项目的主要逻辑文件，如 gltfPipeline.js 和 processGltf.js 等。
• test/: 包含项目的测试文件，位于 spec/ 目录下。
• doc/: 包含生成的文档文件。
• package.json: 项目的配置文件，包含依赖、脚本等信息。
• README.md: 项目的介绍文档。

2. 项目的启动文件介绍

项目的启动文件位于 bin/ 目录下的 gltf-pipeline.js。这个文件是命令行工具的入口点，负责解析命令行参数并调用相应的处理函数。

#!/usr/bin/env node

const yargs = require('yargs');
const gltfPipeline = require('../lib/gltfPipeline');
const processGltf = require('../lib/processGltf');
const glbToGltf = require('../lib/glbToGltf');
const gltfToGlb = require('../lib/gltfToGlb');

// 命令行参数解析
const argv = yargs
    .option('i', {
        alias: 'input',
        describe: 'Input glTF file',
        type: 'string',
        demandOption: true
    })
    .option('o', {
        alias: 'output',
        describe: 'Output file',
        type: 'string'
    })
    .option('d', {
        alias: 'draco',
        describe: 'Apply Draco compression',
        type: 'boolean'
    })
    .help()
    .argv;

// 根据参数调用相应的处理函数
if (argv.draco) {
    processGltf(argv.input, argv.output, { draco: true });
} else {
    gltfPipeline(argv.input, argv.output);
}

3. 项目的配置文件介绍

项目的配置文件是 package.json，它包含了项目的元数据、依赖、脚本等信息。
