three.js几何体之平面缓冲几何体
平面缓冲几何体 PlaneGeometry 是一个用于生成平面几何体的类。构造器:
PlaneGeometry(width : Float, height : Float, widthSegments : Integer, heightSegments : Integer)
其中:
width — 平面沿着X轴的宽度。默认值是 1
height — 平面沿着Y轴的高度。默认值是 1
widthSegments — (可选)平面的宽度分段数,默认值是 1
heightSegments — (可选)平面的高度分段数,默认值是 1
如下代码,我们使用上述几何体绘制了网格状的线框平面矩形:
<style> body { margin: 0; display: grid; place-items: center; } #btnControl { position: absolute; bottom: 20px; } </style> <button type="button" id="btnControl">暂停/继续动画</button> <script type="module"> import * as THREE from 'https://638183.freep.cn/638183/web/ku/three.module.min.js'; const scene = new THREE.Scene; const camera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 0.1, 1000); camera.position.set(0, 0, 10); const renderer = new THREE.WebGLRenderer({ antialias: true }); renderer.setSize(window.innerWidth, window.innerHeight); document.body.appendChild(renderer.domElement); // 绘制平面缓冲几何体图案 const plane = new THREE.Mesh( new THREE.PlaneGeometry(3, 5, 8, 8), // 宽高 3*5,网格 8*8 new THREE.MeshBasicMaterial({ wireframe: true }) // 线框 ); scene.add(plane); const clock = new THREE.Clock(); const animate = () => { requestAnimationFrame(animate); const delta = clock.getDelta(); plane.rotation.y -= delta; renderer.render(scene, camera); }; window.onresize = () => { camera.aspect = window.innerWidth / window.innerHeight; camera.updateProjectionMatrix(); renderer.setSize(window.innerWidth, window.innerHeight); } btnControl.onclick = () => clock.running ? clock.stop() : clock.start(); animate(); </script>
