我正在尝试使用HTML并在页面上绘制一条线.
从我读过的所有内容建议HTML5 canvas标签是最好用的,但是我需要连接到页面上不在canvas标签中的东西的行,所以画布对我不好(想要/需要使用原生JS) .
我写了(从我发现的东西)一个功能,它做我需要的但问题是一旦出现线,页面的其他一切都消失了.
我发现每次我改变JavaScript的风格,但形状都会消失.
删除"document.write"结束时没有任何消失.

if (is_plugin_active(get_home_url() . '/wp-content/plugins/easy-digital-downloads/easy-digital-downloads.php')) {
echo 'plugin is active';
} else {
echo 'plugin is not active';
}
上面的代码回显“插件未激活”，但插件已激活。
我认为问题是我的插件地址的目录。
如何使用Three.js中的新THREE.TextureLoader加载多个纹理？
目前我正在加载我的纹理:
var texture1 = THREE.ImageUtils.loadTexture('texture1.jpg');
var texture2 = THREE.ImageUtils.loadTexture('texture2.jpg');
var texture3 = THREE.ImageUtils.loadTexture('texture3.jpg');
var texture4 = THREE.ImageUtils.loadTexture('texture4.jpg');
var texture5 = THREE.ImageUtils.loadTexture('texture5.jpg');
...
Google Chrome的开发者工具会发出以下警告:
THREE.ImageUtils.loadTexture已被弃用.请改用THREE.TextureLoader().
我尝试使用新的THREE.TextureLoader:
var loader = new THREE.TextureLoader();
loader.load('texture1.jpg',function ( texture1 ) {});
loader.load('texture2.jpg',function ( texture2 ) {});
loader.load('texture3.jpg',function ( texture3 ) {});
loader.load('texture4.jpg',function ( texture4 ) {});
loader.load('texture5.jpg',function ( texture5 ) {});
我究竟做错了什么？
我希望我TextureLoader使用标题授权来加载纹理：
let loader = new THREE.TextureLoader();
loader.headers = { . . . }; // I want this!
let myTex = loader.load('my_authorized_url');
我想将自定义标头传递到通过网络发送的请求中。我看到了这个Loader#setWithCredentials()函数，但我不知道它是如何使用的（或者这是否是我应该使用的）。我应该考虑编写自己的加载程序吗？
编辑：在我看来，ImageLoader源代码中没有可以设置标头的地方。
我想加载cube.obj引用多个cube_*.mtl文件的文件,后者又使用纹理图像*.png(所有资源).加载多个mtl而不是一个mtl的原因是能够动态加载具有相同几何但不同材质的对象.
我找不到这样的例子所以我试图通过加载所有mtl,创建和加载obj 来混合MultiMaterial中的示例(不再受threejs支持)文档和webgl_loader_obj_mtlMultiMaterial:
var resources = 'cube/';
var materialsToLoad = [
'cube_red.mtl',
'cube_green.mtl',
'cube_blue.mtl'
];
var loadedMaterials = [];
var mtlLoader = new THREE.MTLLoader();
mtlLoader.setPath(resources);
for (var i = 0; i < materialsToLoad.length; i++) {
mtlLoader.load(materialsToLoad[i], function(materials) {
materials.preload();
loadedMaterials.push(materials);
});
}
var multi = new THREE.MultiMaterial(loadedMaterials);
var objLoader = new THREE.OBJLoader();
objLoader.setPath(resources);
objLoader.setMaterials(multi); // #1
objLoader.load('cube.obj', function (object) {
scene.add(object);
});
但这不起作用,抛出异常:
Uncaught TypeError: …
