【VTK】vtkjs编译

1、下载vtkjs-master.zip

2、package.json分析

    "size": "size-limit --why --config ./webpack.config.js",
    "validate": "prettier --config ./prettier.config.js --list-different \"Sources/**/*.js\" \"Examples/**/*.js\"",
    "reformat": "prettier --config ./prettier.config.js --write \"Sources/**/*.js\" \"Examples/**/*.js\"",
    "reformat-only": "prettier --single-quote --trailing-comma es5 --print-width 80 --arrow-parens always --write",
    "doc": "kw-doc -c ./Documentation/config.js",
    "doc:www": "npm t -- --single-run && kw-doc -c ./Documentation/config.js -s",
    "doc:publish": "kw-doc -c ./Documentation/config.js -mp",
    "example": "node ./Utilities/ExampleRunner/example-runner-cli.js -c ./Documentation/config.js",
    "build": "webpack-dev-server --config webpack.dev.js",
    "build:release": "webpack --config webpack.prod.js --progress --hide-modules",
    "test": "karma start ./karma.conf.js",
    "test:travis": "karma start ./karma.conf.js --browsers ChromeHeadlessNoSandbox --single-run",
    "test:debug": "karma start ./karma.conf.js --no-single-run",
    "test:firefox": "karma start ./karma.conf.js --browsers Firefox",
    "test:firefox-debug": "karma start ./karma.conf.js --browsers Firefox --no-single-run",
    "commit": "git cz",
    "semantic-release": "semantic-release"

3、文件结构分析

4、编译

npm run build:release

5、测试vtk.js

打开dist目录

双击index.html，浏览器出现

6、代码分析

<!DOCTYPE html>
<html>

<head>
  <title>vtk.js</title>
</head>

<body>
  <script type="text/javascript" src="https://unpkg.com/@babel/polyfill@7.0.0/dist/polyfill.js"></script>
  <script type="text/javascript" src="vtk.js"></script>
  <script type="text/javascript">
    var fullScreenRenderer = vtk.Rendering.Misc.vtkFullScreenRenderWindow.newInstance();
    var actor = vtk.Rendering.Core.vtkActor.newInstance();
    var mapper = vtk.Rendering.Core.vtkMapper.newInstance();
    var cone = vtk.Filters.Sources.vtkConeSource.newInstance();

    actor.setMapper(mapper);
    mapper.setInputConnection(cone.getOutputPort());

    var renderer = fullScreenRenderer.getRenderer();
    renderer.addActor(actor);
    renderer.resetCamera();

    var renderWindow = fullScreenRenderer.getRenderWindow();
    renderWindow.render();

  </script>
</body>
