Javascript 使用THREE.TextureLoader时出现语法问题
我正在尝试一个全景查看器代码，它的3.js版本是r68，为了使用raycaster函数，我将3.js版本更新为r121。 当我修改代码时出现问题：Javascript 使用THREE.TextureLoader时出现语法问题,javascript,three.js,Javascript,Three.js,我正在尝试一个全景查看器代码，它的3.js版本是r68，为了使用raycaster函数，我将3.js版本更新为r121。 当我修改代码时出现问题： var texture = THREE.ImageUtils.loadTexture('img/pano2.jpg', new THREE.UVMapping(), function() { init(); animate();
