- 安装依赖
pip install flask
- 创建Flask应用
创建一个基本的Flask应用，并设置路由来处理不同的文件类型。
from flask import Flask, render_template, send_from_directory
app = Flask(name)
设置静态文件路径
app.static_folder = 'static'
@app.route('/')
def index():
return render_template('index.html')
@app.route('/view/360')
def view_360():
return render_template('360_viewer.html')
@app.route('/view/stl')
def view_stl():
return render_template('stl_viewer.html')
@app.route('/static/<path:filename>')
def static_files(filename):
return send_from_directory(app.static_folder, filename)
if name == 'main':
app.run(debug=True)
- 创建HTML模板
在`templates`文件夹中创建HTML模板文件。
index.html

<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

const renderer = new THREE.WebGLRenderer();

document.getElementById('model').appendChild(renderer.domElement);
const loader = new THREE.STLLoader();
loader.load('/static/model.stl', function (geometry) {
const material = new THREE.MeshPhongMaterial({ color: 0x00ff00, specular: 0x111111, shininess: 200 });
const mesh = new THREE.Mesh(geometry, material);
scene.add(mesh);
const ambientLight = new THREE.AmbientLight(0x404040);
scene.add(ambientLight);
const directionalLight = new THREE.DirectionalLight(0xffffff, 0.5);
directionalLight.position.set(1, 1, 1);
scene.add(directionalLight);
camera.position.z = 100;
const animate = function () {
requestAnimationFrame(animate);
mesh.rotation.x += 0.01;
mesh.rotation.y += 0.01;
renderer.render(scene, camera);
};
animate();
});

- 放置静态文件
在static文件夹中放置你的360全景图和STL模型文件。例如：
-
static/360_image.jpg：360全景图
-
static/model.stl：STL模型文件
- 运行应用
在终端中运行你的Flask应用：
python app.py
- 访问应用
打开浏览器，访问http://127.0.0.1:5000/，你将看到选择浏览模式的页面。点击链接即可查看360全景图或STL模型。
总结
通过以上步骤，你可以使用Flask实现一个简单的Web应用，用于浏览360全景图和STL模型。你可以根据需要进一步扩展和美化这个应用。
