Struct Axial 

pub struct Axial {
    pub start: Point,
    pub end: Point,
    pub t_min: f32,
    pub t_max: f32,
    pub extend_start: bool,
    pub extend_end: bool,
}

A type 2 shading’s geometry.

Fields

start: Point

The axis’s start point.

end: Point

The axis’s end point.

t_min: f32

/Domain’s low bound.

t_max: f32

/Domain’s high bound.

extend_start: bool

Whether the gradient continues past the start point.

extend_end: bool

Whether it continues past the end point.

Implementations

impl Axial

pub fn axis_len_squared(&self) -> f64

The squared axis length, which is the normalizing divisor.

Zero for a degenerate axis, which is the case the caller must handle.

pub fn position(&self, p: Point) -> Option<f32>

The parametric position of a point in the shading’s own space.

None for a degenerate axis, where the C++ divides by zero. A caller treating that as “out of range at the start” reproduces what the undefined cast produces in practice.

Trait Implementations

impl Clone for Axial

fn clone(&self) -> Axial
