This is a repeating pattern of basically ellipses rotated alternately at +- 45 degrees. I'm trying to implement this one using vex only (yay coding!) by dissecting the soft dots sop. So far I've been able to replicate the dots and add the second "layer" of hashmarks in but I'm not able to rotate the ellipses properly. I've obtained a 30 degree rotation, as shown below.
So far I've tried to rotate the UV coordinates based on a matrix before the ellipses are produced, rotate the ellipses using a matrix after they are produced and finally by altering the equation that is producing the ellipses. The latter has been the most successful but only stretches the shapes rather than physically rotating them.
