This is like that SAT question, how many revolutions does a circle with 1/3 the radius of a larger circle make around the larger circle.

Consider the square shown below on the left, which has been textured with the image shown on the right. What are the texture coordinates of the vertices a, b, c, and d?

Does anyone know how to answer this?

You could rotate the UV coordinates by pi/4.0. You'll also have to scale by sqrt(2.0).

Also guessing the center of the star is [0.5, 0.5] so

```
a = [-0.5+x, 0.5+y] 
b = [0.5+x, 1.5+y] 
c = [1.5+x, 0.5+y] 
d = [0.5+x, -0.5+y]

```

$ \forall x, y \in \mathbb{Z} $

I'm guessing that the centre of the star has texture coordinates $[0.5, 0.5]$ then $a,b,c,d$ all have the same texture coordinate $[0.5, 0.5]$.
