javascript - 我需要隐藏 ThreeJS 框基元上的边缘

Question

我需要使用 ThreeJS 隐藏框基元中显示的边缘。仅当我在脸上放置纹理时才会绘制这些。

我尝试过许多选项，例如wireframe=false，但边缘仍然被绘制。

这是代码:

        var container, stats;
        var camera, scene, renderer;

        var canvasWidth = 500; 
        var canvasHeight = 500;
        var windowHalfX = 100;
        var windowHalfY = 100;

        container = document.createElement( 'div' );
        document.body.appendChild( container );

        // Camera
        camera = new THREE.OrthographicCamera( canvasWidth / - 2, canvasWidth / 2, canvasHeight / 2, canvasHeight / - 2, - 500, 5000 );

        // Scene
        scene = new THREE.Scene();

        camera.position.x = 200;
        camera.position.y = 200;
        camera.position.z = 200;

        camera.lookAt( scene.position );

        // Renderer
        renderer = new THREE.CanvasRenderer();
        renderer.setClearColor( "#fff" );
        renderer.setSize( canvasWidth, canvasHeight );

        container.appendChild( renderer.domElement );

        var size = 100;
        geometry = new THREE.BoxGeometry( size, size, size ); 

        material = new THREE.MeshBasicMaterial({ 
            color: "#0000ff", 
            side: THREE.DoubleSide,
            wireframe: false
        });

        // Comment this line to paint a single color cube
        material = new THREE.MeshLambertMaterial({ map: THREE.ImageUtils.loadTexture("http://upload.wikimedia.org/wikipedia/commons/8/81/Color_icon_black.png") });

        mesh = new THREE.Mesh( geometry, material );
        scene.add( mesh );

        var draw = function() {
            requestAnimationFrame( draw );
            renderer.render( scene, camera );
        }

        draw();

我已经解决了更改此行的问题

renderer = new THREE.CanvasRenderer();

对于这个其他

renderer = new THREE.WebGLRenderer();

其他可能的解决方案，正如 WestLangley 上面评论的那样，是将这一行与 CanvasRenderer 一起使用

material.overdraw = 0.5; // or some number between 0 and 1
