Three.js无法显示我的纹理。

Question

我需要制作一个带有纹理的球体。我在WebGL和Three.js方面非常新手。问题是我看到了一个白色的球体，但没有纹理。由于我是新用户，无法提交图片。

代码部分如下：

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 );

        }

提前感谢您。

Answer 1

应该是这样的：

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

由于这是在Google搜索结果中出现的第一页，所以我将发布我的解决方案。我在正方形上绘制纹理，但实际上正方形被向后旋转，因此相机看到了没有纹理的正方形背面，在修复旋转后一切正常运作。

   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);
     });
