Struct TangentFrame 

Source 
pub struct TangentFrame {
    pub normal: [f64; 3],
    pub tangent_u: [f64; 3],
    pub tangent_v: [f64; 3],
}
Expand description

An orthonormal tangent frame at a surface point.

Fields§

§normal: [f64; 3]

Surface normal (unit vector).

§tangent_u: [f64; 3]

Tangent along u direction (unit vector).

§tangent_v: [f64; 3]

Tangent along v direction (unit vector, ≈ normal × tangent_u).
