bytev-charts/lib/plugin/three.js/examples/jsm/postprocessing/Pass.js

基于echarts和JavaScript及ES6封装的一个可以直接调用的图表组件库，内置主题设计，简单快捷，且支持用户自定义配置； npm 安装方式: npm install bytev-charts 若启动提示还需额外install插件,则运行 npm install @babel/runtime-corejs2 即可;

import _Object$assign from "@babel/runtime-corejs2/core-js/object/assign";
import _Object$defineProperty from "@babel/runtime-corejs2/core-js/object/define-property";
import { OrthographicCamera, PlaneBufferGeometry, Mesh } from "../../../build/three.module.js";

  // if set to true, the pass is processed by the composer
  this.enabled = true; // if set to true, the pass indicates to swap read and write buffer after rendering

  this.needsSwap = true; // if set to true, the pass clears its buffer before rendering

  this.clear = false; // if set to true, the result of the pass is rendered to screen. This is set automatically by EffectComposer.

  this.renderToScreen = false;
}

_Object$assign(Pass.prototype, {
  setSize: function
    /* width, height */
  setSize() {},
  render: function
    /* renderer, writeBuffer, readBuffer, deltaTime, maskActive */
  render() {
    console.error('THREE.Pass: .render() must be implemented in derived pass.');
  }
}); // Helper for passes that need to fill the viewport with a single quad.
