【问题描述】：
在测试 Rhino 和 Three 之间的导入/导出时，我在可视化一个相当复杂的 obj 文件时遇到了一些问题。在对网格进行三角剖分后，我从 Rhino 导出了 obj。
问题与材质无关：没有材质，有材质或/和在 Three 内应用了纹理。
我尝试从 Rhino 导入的几何图形的 Jpeg 与 Three.js 上的结果：http://goo.gl/1WMGSu
如您所见，存在一些奇怪的深度问题，尤其是取决于相机位置。 我对该主题进行了长时间的研究，但没有找到解决方案。我将在 StackOverflow 上附加一些我已经关注的其他主题。
我自己也尝试在 Rhino 中检查和翻转法线，但没有成功。
我的脚本（根据 Gaitat 建议更新）：
