Struct UvMap 

pub struct UvMap {
    pub m: [[Scalar; 2]; 2],
    pub shift: Vector2,
}

An affine map of (u, v) that takes each parameter to one parameter: x' = m x + shift, m diagonal, or — the parameters swapped — anti-diagonal.

Fields

m: [[Scalar; 2]; 2]

shift: Vector2

Implementations

impl UvMap

pub fn apply(&self, uv: Vector2) -> Vector2

Where uv goes.

pub fn apply_to(&self, curve: &NurbCurve2D) -> GeopResult<NurbCurve2D>

The pcurve curve mapped: each homogeneous control point (w x, w) to (m (w x) + w shift, w), linear in it, so the mapped curve is exactly the curve mapped, rational or not.
