如何使用 react 和 three.js 在网站渲染自己的3D模型
create-react-app my-3d-model #or yarn create react-app my-3d-model 然后安装 @react-three/fiber 和 @react-three/drei npm install three @react-three/fiber @react-three/drei #or yarn add three @react-three/fiber @react-three /drei 将模型转换为 React 组件 完成之后，继续并运行以下命令，使用 gltfjsx 转换成 react 组件格式。 model.glb 转换后的内容类似于以下代码 import React, { useRef } from 'react' import { useGLTF } from '@react-three/drei from 'react' import { Canvas } from '@react-three/fiber' import { OrbitControls } from '@react-three/drei

Three.js实例化技术：高效渲染数千3D对象
使用drei/instances可以快速实现实例化：import { Instance, Instances } from "@react-three/drei"const boxCount = 1000function 多组实例要渲染森林场景，可能需要不同的实例组：import { createInstances } from "@react-three/drei"const boxCount = 1000const

true 也可以使用size或者length方法，判断哈希的大小是否为0： dictionary = { "one" => "eins", "two" => "zwei", "three" => "drei ---- false false 通过delete方法删除键值对： dictionary = { "one" => "eins", "two" => "zwei", "three" => "drei " } dictionary.delete("one") puts dictionary # ---- 输出结果 ---- {"two"=>"zwei", "three"=>"drei"} 需要注意的是
