问题 I really need to understand how skew(xdeg) function works all research does not seem to explain how the x angle affecting the other points and distorts it like that, I need to know if there any mathematical formula it or a way to be able to expect the result of using a specific degree. ps. I already read tons of docs which the best one of them was the DevDocs which say This transformation is a shear mapping (transvection) that distorts each point within an element by a certain angle in the
