Question

有没有人知道为什么以下中断为three.min.js从r87更新为r88或r89？这只是使用来自three.js相关培训网站的基础知识。使用r87或更早版本，将显示一个多维数据集。使用r88或r89，只有一块黑色帆布。我在Chrome，Firefox和＆amp; IE。

        scene = new THREE.Scene();

        renderer = new THREE.WebGLRenderer({canvas: canvas, antialias: true});

        camera = new THREE.PerspectiveCamera(60, canvas.width / canvas.height, 0.1, 400);

        camera.lookAt({"x": 50.0, "y": 50.0, "z": 50.0});

        var light = new THREE.PointLight(0xffff00);
        light.position.set(50, 50, 50);

        var geometry = new THREE.BoxGeometry(50, 50, 50);

Answer 1

以下是无效的three.js代码，并且从未有效的three.js代码：

camera.lookAt( { "x": 50.0, "y": 50.0, "z": 50.0 } );

使用

camera.lookAt( 50, 50, 50 );

或

camera.lookAt( myVector3 );

three.js r.90

基本场景中断从three.js v87过渡到v88或v89
