Question

我需要制作一个带有纹理的球。我是WebGL和Three.js的新手。问题是我看到了一个白色球体而不是它上面的纹理。作为新用户，我无法提交图片。

代码部分是：

function init() {

            canvas = document.getElementById( 'canvas' ); 


            camera = new THREE.PerspectiveCamera( 90, window.innerWidth / window.innerHeight, 1, 10000 );
            camera.position.z = 1000;



            scene = new THREE.Scene();

                            camera.lookAt (scene.position); 


                            var llum = new THREE.DirectionalLight();
                            llum.intensity=50;


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

                            llum.lookAt(scene.position);

                            scene.add(llum);



                            var texture = THREE.ImageUtils.loadTexture('ull.jpg');


            texture.needsUpdate = true;

            var material = new THREE.MeshBasicMaterial( texture );

            var quality = 16, step = 1024 / quality;

            var geom = new THREE.SphereGeometry(500,100,100);



            mesh = new THREE.Mesh( geom, material );


            scene.add( mesh );


            renderer = new THREE.WebGLRenderer({ antialias: true});
            renderer.setSize( window.innerWidth, window.innerHeight );

            canvas.innerHTML = ""; 

                            //Afegim al canvas el que hem de renderitzar
            canvas.appendChild( renderer.domElement );



            document.addEventListener( 'mousemove', onDocumentMouseMove, false );


            window.addEventListener( 'resize', onWindowResize, false );

        }

提前致谢。

Answer 1

应该是这样的：

var material = new THREE.MeshBasicMaterial( { map: texture } );

Answer 2

由于这是Google搜索结果中显示的第一页，因此我将在我的案例中发布解决方案。我在正方形上绘制纹理但是正方形实际上是向后旋转所以相机在没有纹理的情况下看到正方形的背面，在固定旋转之后一切正常。

   var geometry = new THREE.PlaneGeometry(FLOOR_SIZE, FLOOR_SIZE, 10, 10);

    var loader = new THREE.TextureLoader();
    loader.load('images/floor.jpg', function ( texture ) {
        var material = new THREE.MeshBasicMaterial({
            map: texture, 
            overdraw: 0.5
        });

        var floor = new THREE.Mesh( geometry, material );

        // ROTATION THAT MADE SQUARE INVISIBLE WAS Math.PI/2

        floor.rotation.x = -Math.PI/2;
        floor.position.y = -0.1;
        scene.add(floor);
     });

Three.js没有显示我的纹理
