好的,以下是利用 ThreeJS 中的基本几何体模型创建一个简单的木偶人的代码和步骤:
1. 引入 ThreeJS 库和一个渲染器、相机、场景:
```javascript
import * as THREE from 'three';
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
const camera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 1, 1000);
camera.position.set(0, 0, 5);
const scene = new THREE.Scene();
```
2. 创建一个球体作为木偶人的头部:
```javascript
const headGeometry = new THREE.SphereGeometry(0.5, 32, 32);
const headMaterial = new THREE.MeshBasicMaterial({ color: 0xff0000 });
const head = new THREE.Mesh(headGeometry, headMaterial);
head.position.set(0, 1.5, 0);
scene.add(head);
```
3. 创建一个立方体作为木偶人的身体:
```javascript
const bodyGeometry = new THREE.BoxGeometry(1, 1, 0.5);
const bodyMaterial = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
const body = new THREE.Mesh(bodyGeometry, bodyMaterial);
body.position.set(0, 0.5, 0);
scene.add(body);
```
4. 创建两个多面体作为木偶人的手臂:
```javascript
const armGeometry = new THREE.TetrahedronGeometry(0.3);
const armMaterial = new THREE.MeshBasicMaterial({ color: 0x0000ff });
const leftArm = new THREE.Mesh(armGeometry, armMaterial);
leftArm.position.set(-0.8, 0.5, 0);
const rightArm = new THREE.Mesh(armGeometry, armMaterial);
rightArm.position.set(0.8, 0.5, 0);
scene.add(leftArm, rightArm);
```
5. 创建两个多面体作为木偶人的腿:
```javascript
const legGeometry = new THREE.OctahedronGeometry(0.3);
const legMaterial = new THREE.MeshBasicMaterial({ color: 0xffff00 });
const leftLeg = new THREE.Mesh(legGeometry, legMaterial);
leftLeg.position.set(-0.3, -0.5, 0);
const rightLeg = new THREE.Mesh(legGeometry, legMaterial);
rightLeg.position.set(0.3, -0.5, 0);
scene.add(leftLeg, rightLeg);
```
6. 渲染场景:
```javascript
function animate() {
requestAnimationFrame(animate);
head.rotation.x += 0.01;
head.rotation.y += 0.01;
body.rotation.x += 0.01;
body.rotation.y += 0.01;
leftArm.rotation.z += 0.02;
rightArm.rotation.z -= 0.02;
leftLeg.rotation.z -= 0.02;
rightLeg.rotation.z += 0.02;
renderer.render(scene, camera);
}
animate();
```
完成了以上步骤,就可以在浏览器中看到一个简单的木偶人了。你可以根据自己的需求修改模型的形状、颜色和位置等属性,创造出更加有趣的木偶人模型。
