我想在平面上添加重复水平和垂直的纹理。问题是,当我尝试应用纹理时,它始终是黑色的。我没有任何错误,并且我已经尝试添加一些灯,但是问题仍然存在。我不知道如何解决...这是我做的:

window.onload = function init()
{
  scene = new THREE.Scene();

  var camera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 0.1, 1000);
  camera.position.x = -30;
  camera.position.y = 40;
  camera.position.z = 30;
  camera.lookAt(scene.position);

  var light = new THREE.AmbientLight( 0x404040 ); // soft white light
  scene.add( light );

  var spotlight = new THREE.SpotLight( 0xffffff);
  spotlight.position.set( -50, 40, 0 );
  scene.add( spotlight );


var axes = new THREE.AxisHelper( 20 ); scene.add(axes);

  var renderer = new THREE.WebGLRenderer();
  renderer.setClearColor(0xEEEEEE);
  renderer.setSize(window.innerWidth, window.innerHeight);

  desenhaMapa();

  document.body.appendChild( renderer.domElement );
  renderer.render(scene, camera);

}

    function desenhaMapa()
{
  labirinto = new THREE.Object3D();

  var texturaPlano = new THREE.TextureLoader().load("texturaPac.jpg");

  geometryPlano = new THREE.PlaneGeometry(50,50);
  materialPlano = new THREE.MeshPhongMaterial( {map: texturaPlano} );
  var planoPacMan = new THREE.Mesh(geometryPlano,materialPlano);
  planoPacMan.rotation.x = -0.5 * Math.PI;
  scene.add(planoPacMan);
}


有什么建议么?

最佳答案

TextureLoader.load()是异步方法。这就是为什么它有一个onload参数的原因。

您正在加载纹理之前调用render()。一种解决方案是在加载程序回调中调用render()

var loader = new THREE.TextureLoader();

var texture = loader.load( 'myTexture.jpg', function ( texture ) {

    renderer.render( scene, camera );

} );


另一个解决方案是具有动画循环。但这对于静态场景不是必需的。
