我使用cube
创建了three.js
。但是如何将click
事件添加到cube
?
是否需要任何其他js
库,或者我们可以直接将事件添加到对象中?
这是我的代码:
$(function () {
var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera( 50, window.innerWidth / window.innerHeight, 0.1, 1000);
var webGLRenderer = new THREE.WebGLRenderer({ antialias : true });
webGLRenderer.setClearColor (0xEEEEEE, 1.0);
webGLRenderer.setSize ( window.innerWidth, window.innerHeight );
webGLRenderer.shadowMapEnabled = true;
var cube = createMesh(new THREE.CubeGeometry(5, 5, 5), "floor-wood.jpg" );
cube.position.x = -12;
scene.add(cube);
// console.log(cube.geometry.faceVertexUvs);
var step = 0;
render ();
camera.position.x = 00;
camera.position.y = 12;
camera.position.z = 28;
camera.lookAt(new THREE.Vector3(0, 0, 0));
var ambiLight = new THREE.AmbientLight(0x141414)
scene.add(ambiLight);
var light = new THREE.DirectionalLight();
light.position.set(20, 30, 20);
scene.add(light);
function createMesh (geo, imgFile) {
var texture = THREE.ImageUtils.loadTexture ("images/" + imgFile);
var mat = new THREE.MeshPhongMaterial();
mat.map = texture;
var mesh = new THREE.Mesh ( geo, mat);
return mesh;
}
function render () {
cube.rotation.y = step;
cube.rotation.x = step;
requestAnimationFrame ( render );
webGLRenderer.render( scene, camera );
}
$('#webGL-output')
.append(webGLRenderer.domElement);
});

您无法将事件直接附加到网格,因为它不是DOM元素。
有一个名为threex.domevents的Three.js扩展名,允许您将所有鼠标事件附加到网格中,例如点击,悬停,鼠标悬停/鼠标移出。
当你触发DOM事件时,它的作用基本上是在你的网格上进行光线投射,非常简单。它适用于最新的r71。
用法:
var domEvents = new THREEx.DomEvents(camera, renderer.domElement)
domEvents.addEventListener(mesh, 'click', function(event){
console.log('you clicked on mesh', mesh)
}, false)
