我正在尝试使用Three.js创建一个对象加载器,但我注意到质量太低而且同时使用了太多的CPU。
当我使用我的版本时,场景看起来像这样:
但是当我使用this website加载它时,看起来好多了并且使用的CPU更少:
我加载此对象的JavaScript是:
var camera;
var scene;
var renderer;
var controls;
var container = document.getElementById('webgl');
var WIDTH = container.clientWidth;
var HEIGHT = container.clientHeight;
var ASPECT = WIDTH / HEIGHT;
var ANGLE = 45;
var container = document.getElementById('webgl');
if (Detector.webgl) {
main();
} else {
var warning = Detector.getWebGLErrorMessage();
document.getElementById('webgl').appendChild(warning);
}
function main(){
//Scene
scene = new THREE.Scene();
//Camera
camera = new THREE.PerspectiveCamera(
ANGLE, // field of view
ASPECT, // aspect ratio
10, // near clipping plane
100000 // far clipping plane
);
camera.position.x = 500;
camera.position.y = 200;
camera.position.z = 500;
camera.lookAt(new THREE.Vector3(100, 100, 100));
//Renderer
renderer = new THREE.WebGLRenderer();
var ambientLight = getAmbientLigth(1);
scene.add(ambientLight);
scene.background = new THREE.Color( 0xc3c3c3 );
renderer.setSize(WIDTH, HEIGHT);
renderer.shadowMap.enabled = true;
document.getElementById('webgl').appendChild(renderer.domElement);
controls = new THREE.OrbitControls( camera, renderer.domElement );
controls.maxPolarAngle = Math.PI/2;
controls.enableKeys = true;
loadObject();
update(renderer, scene, camera, controls);
}
function getAmbientLigth(intensity, color) {
color = color === undefined ? 'rgb(255, 255, 255)' : color;
var light = new THREE.AmbientLight(color, intensity);
return light;
}
function loadObject() {
var mtlLoader = new THREE.MTLLoader();
var objLoader = new THREE.OBJLoader();
mtlLoader.setPath( 'objects/Blue_shed/' );
mtlLoader.load('blueShed.mtl', function( materials ) {
materials.isMultiMaterial = true;
materials.preload();
objLoader.setMaterials( materials );
objLoader.setPath( 'objects/Blue_shed/' );
objLoader.load( 'blueShed.obj', function ( object ) {
object.name = 'cute-house';
object.receiveShadow = true;
object.castShadow = true;
object.scale.set( 30, 30, 30);
scene.add( object );
} );
});
}
function update(renderer, scene, camera, controls) {
controls.update();
renderer.render(scene, camera);
requestAnimationFrame(function() {
update(renderer, scene, camera, controls);
});
}
我使用renderer.setSize
来提高渲染器的分辨率,这有点帮助但仍然没有第二张图像那么好,并且仍然使用了太多的CPU。
有什么想法吗?有没有设置或我没有正确设置的东西?我看到该网站使用的是JSON加载程序,但我认为这与此问题无关,但我提到它以防万一。
