【VTK.js】第一个vtk.js程序

使用vtk.js预构建的脚本文件来构建我们的第一个应用程序。

新建index.html文件，写入以下内容：

<!DOCTYPE html>
<html>
    <body>
        <script type="text/javascript" src="https://unpkg.com/vtk.js"></script>
        <script type="text/javascript">
          // --------------------------------------------------------------------------
          // Example code
          // --------------------------------------------------------------------------
          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>
</html>

运行结果：
在这里插入图片描述

这里会首先链接到远程vtk.js的脚本，为了加快链接速度，我们可以将该文件下载保存在本地并修改代码如下可得到相同的效果：

<!DOCTYPE html>
<html>
    <body>
        <script type="text/javascript" src="js/vtk.js"></script>
        <script type="text/javascript">
          // --------------------------------------------------------------------------
          // Example code
          // --------------------------------------------------------------------------
          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>
</html>
