Struct GlassProfileCurve 

pub struct GlassProfileCurve { /* private fields */ }

A normalized center-to-edge cubic cross-section.

Positions and heights are both authored in 0..1. Tangents are generated with a monotonicity-preserving cubic law so interactive sliders cannot introduce unrequested oscillations between knots.

Implementations

impl GlassProfileCurve

pub fn from_points( points: &[(f32, f32)], ) -> Result<GlassProfileCurve, GlassProfileError>

pub fn knots(&self) -> &[GlassProfileKnot]

pub fn evaluate(&self, position: f32) -> (f32, f32)

Evaluates (height, d_height/d_position) at a normalized coordinate.
