Struct Placement 

pub struct Placement {
    pub origin: Vector3,
    pub e1: Vector3,
    pub e2: Vector3,
    pub n: Vector3,
}

Where a flat lies: sheet point (x, y) at origin + x e1 + y e2, its unit normal n = e1 × e2 pointing from its A side to its B side. e1, e2 and n are orthonormal.

Fields

origin: Vector3

e1: Vector3

e2: Vector3

n: Vector3

Implementations

impl Placement

pub fn point(&self, p: &Vector2) -> Vector3

The sheet point p in space.

pub fn direction(&self, d: &Vector2) -> Vector3

The sheet direction d in space.

pub fn curve(&self, curve: &NurbCurve2D) -> GeopResult<NurbCurve3D>

The sheet curve curve in space: exact, an affine map of its control points.

pub fn offset(&self, t: Scalar) -> Self

The same placement t further along the normal: the B side’s.

pub fn coordinate_system(&self) -> GeopResult<CoordinateSystem>

As a coordinate system: u = e1, v = e2, w = n.
