You are trying to use only 8 vertices. To get correct texturing you must use 12 separate triangles, each of them with the "correct" texture coordinates. The thing is when you're trying to do the planar map onto something homeomorphic to the sphere (e.g. , a cube in your case), you will get "troubles" like this.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
