我有一个带铁路灯的小三人场景。使用Blender创建并导出模型。
这是我的代码:
var scene, camera, renderer, ambientLight, directionalLight, spotLight, model, progress;
var stats, toolbox, loader;
var SCREEN_WIDTH, SCREEN_HEIGHT;
function init(model) {
//vars
container = document.getElementById('webGL_container');
toolbox = document.getElementById('toolbox');
loaderDiv = document.getElementById('loader');
//scene
scene = new THREE.Scene();
scene.fog = new THREE.FogExp2( 0x929599, 0.001 );
//progress
progress = new THREE.LoadingManager();
progress.onProgress = function ( item, loaded, total ) {
//console.log( item, loaded, total );
};
//loader
loader = new THREE.ObjectLoader(progress);
loader.load(model, function (obj) {
// executes when scene is loaded
scene.add(obj);
loaderDiv.style.display = 'none';
cameraControls.enabled = true;
});
//camera
camera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 1, 150);
camera.position.set(0,10,-10);
//light
ambientLight = new THREE.AmbientLight( 0xffffff, 0.1 );
scene.add(ambientLight);
directionalLight = new THREE.DirectionalLight( 0xffffff, 1.1);
directionalLight.position.set( 100, 200, 150 );
scene.add(directionalLight);
spotLight = new THREE.SpotLight( 0xFFAA88 );
spotLight.position.set( 10, 25, 15);
spotLight.castShadow = true;
spotLight.shadow.bias = 0.001;
spotLight.shadow.camera.near = 10;
spotLight.shadow.camera.far = 100;
spotLight.shadow.mapSize.width = 2048;
spotLight.shadow.mapSize.height = 2048;
scene.add( spotLight );
var helper = new THREE.CameraHelper( spotLight.shadow.camera );
scene.add( helper );
//renderer
renderer = new THREE.WebGLRenderer({
antialias: true, alpha: true
});
renderer.setPixelRatio( window.devicePixelRatio );
renderer.setSize(window.innerWidth, window.innerHeight);
renderer.setClearColor( scene.fog.color );
renderer.gammaInput = true;
renderer.gammaOutput = true;
renderer.setFaceCulling(THREE.CullFaceNone);
//shadow
renderer.shadowMap.enabled = true;
renderer.shadowMap.type = THREE.PCFSoftShadowMap;
//
container.appendChild(renderer.domElement);
//controls
cameraControls = new THREE.OrbitControls( camera, renderer.domElement );
cameraControls.target.set(0, 0, 0);
cameraControls.enablePan = true;
cameraControls.enabled = false;
//stats
stats = new Stats();
toolbox.insertBefore(stats.domElement, toolbox.children[1]);
animate();
}
//render
function render() {
renderer.clear();
renderer.render(scene, camera);
}
//animate
function animate() {
stats.begin();
requestAnimationFrame(animate);
render();
cameraControls.update();
stats.end();
}
//resize scene
window.onresize = function () {
SCREEN_WIDTH = window.innerWidth;
SCREEN_HEIGHT = window.innerHeight;
camera.aspect = SCREEN_WIDTH / SCREEN_HEIGHT;
camera.updateProjectionMatrix();
renderer.setSize(SCREEN_WIDTH, SCREEN_HEIGHT);
};

我是在JSFiddle上发布运行时代码的菜鸟,所以完整的代码在这里: https://drive.google.com/open?id=0BwCG1m_fANZmb0UxYVE5OUlfYzQ
我得到的,运行此代码[screenshot]: Strange shadows
我尝试过使用spotLight.shadow.bias = 0.001;
,但没有任何帮助。
如果物体内部没有任何面孔,它看起来不那么丑陋(上限光线),但如果它(光线下限),它看起来很可怕。
在Blender中,我试图翻转,重新计算对象的正常情况,但仍无用。
非常感谢,对于GDrive中的代码感到抱歉。
