在使用 G 开发时,有很多通用的第三方工具可以辅助我们开发调试。

stats.js

stats.js 常用于展示 FPS。配合 G 使用时可以监听 CanvasEvent 画布事件,在每一帧结束时更新:

import { CanvasEvent } from '@antv/g';
// 创建 stats
const stats = new Stats();
stats.showPanel(0);
const $stats = stats.dom;
$stats.style.position = 'absolute';
$stats.style.left = '0px';
$stats.style.top = '0px';
const $wrapper = document.getElementById('container');
$wrapper.appendChild($stats);
// 在每一帧结束时刷新帧数
canvas.addEventListener(CanvasEvent.AFTER_RENDER, () => {
stats.update();
});

Spector.js

如果使用 g-webgl 作为渲染器,可以安装 Chrome 浏览器插件 Spector.js,捕获当前帧执行的所有 WebGL API:
