【3DGS】SuperSplat本地运行+修改监听端口+导入ply模型+修剪模型+在线渲染3DGS网站推荐

SuperSplat官网代码：https://github.com/playcanvas/supersplat

本地安装和运行

1. Clone the repository:

   git clone https://github.com/playcanvas/supersplat.git
   cd supersplat

2. Install dependencies:

   npm install

3. Build SuperSplat and start a local web server:

   npm run develop

修改监听端口

cd supersplat

找到supersplat/package.json

主要修改"serve"，原本为"serve dist -C"，修改为"serve dist -C -p 3001"

    "scripts": {
        "build": "rollup -c",
        "watch": "rollup -c -w",
        "serve": "serve dist -C -p 3001",
        "develop": "concurrently --kill-others \"npm run watch\" \"npm run serve\"",
        "develop:local": "cross-env ENGINE_PATH=../engine npm run develop",
        "build:local": "cross-env ENGINE_PATH=../engine npm run build",
        "watch:local": "cross-env ENGINE_PATH=../engine npm run watch",
        "lint": "eslint src"
    },

这里develop会执行watch和serve

watch会对代码进行打包，serve才是启动，如果已经执行了watch则不需要重复执行，修改serve后执行下列命令：

npm run serve

这样就可以用http://172.17.0.2:3001/打开了，同时避免和其他服务的端口冲突

导入ply模型

在文件->导入这里，选择ply文件

修剪模型

下方的选择工具进行选择，然后按下键盘的delete按键即可对3DGS文件进行修剪
