我在使用示例代码加载obj文件时遇到问题.加载示例文件male02.obj时没有问题,但是当我插入文件时,不显示对象.使用Python转换器脚本和JSONLoader时遇到了同样的问题.
这是OBJLoader的所有代码

我使用的是最新版本的three.js(49).
这是我试图加载https://dl.dropbox.com/u/23384412/originalMeanModel.obj的obj文件的链接
我注意到当我尝试JSONLoader时导出的JSON文件没有任何法线,颜色或uv.这在Blender或MeshLab中查看文件时不会影响,但是会对three.js产生影响吗？
如果有人可以帮助我,将不胜感激.
提前致谢.
解决方法:
必须根据模型的位置和尺寸设置对象和摄像机位置.
“评论”所有这些行：
camera.position.z = 100;
...
object.position.y = - 80;
...
document.addEventListener( 'mousemove', onDocumentMouseMove, false );
并开始播放代码,更改相机位置：
camera.position.z = 2;
