Flash 纹理映射的三角形看起来很糟糕
我有一个用 PaperVision3D 制作的 3D 立方体。
每个“边”由 2 个三角形组成。
我有不同的纹理“材料”映射到每一面。
当我旋转立方体时，纹理会像两个三角形之间的倒置 v 一样倾斜。当直视一张脸时，它看起来还不错，但开始旋转并且它开始扭曲纹理。
如何使 Flash 中的纹理映射看起来像 DirectX？
I have a 3D cube made with PaperVision3D.
Each "side" is made of 2 triangles.
I have a different texture "material" mapped to each side.
When I rotate the cube the texture is skewed like '/\' an upside down v between both triangles. When looking at a face straight on it looks ok but start to rotate and it starts to skew the textures.
How do you make texture mapping in Flash look like DirectX?

PaperVision3D 不使用“真正的”3D 纹理，它使用称为仿射映射的东西< /a> 这是一个 hack。
为了获得更好的结果，您需要将立方体划分为尽可能多的三角形，而不是每个面仅使用两个三角形。
PaperVision3D doesn't use "real" 3d texturing, it uses something called affine mapping which is a hack.
In order to achieve better results you need to partition your cube to as many triangles as possible instead of using just two triangles per face.
我遇到了同样的问题，我在每个平面上使用了 2 个多边形。我将其提高到 4，看起来很棒 - 边缘没有倾斜，并且在再次看到扭曲之前我可以拥有的多边形数量最少。
I had the same problem, I was using 2 poly's to each plane. I upped it to 4 and it looks great - no skewing on the edges and the least amount of polygons I can have before I see the scewing again.
