I have a question that is bothering me for weeks! Is there any way of applying textures to 3D convex polygons, independently of their orientation in the 3D world. I am working with XNA 4.0 if it's relevant

I'm not expecting an easy way out, just a clean solution to solve my current problem. Does anyone made something similar to that?!

Thanks in advance, for your concern and time!

形状的自动生成纹理坐标并不容易......我有一个不是最好的想法，但也许它可以帮助你

如果形状位于平面上，您可以创建一个包含该形状的正方形，很容易获得 [0..1] 范围内的纹理坐标，在平面中的正方形内插值顶点位置。
