Struct Curve2DNorm 

pub struct Curve2DNorm { /* private fields */ }

A normalized 2D curve for transfer functions and easing curves.

Both x and y values are in the range [0.0, 1.0].

Usage

Use sample(x) to get the y-value at any x position:

use plottery_project::Curve2DNorm;

let curve = Curve2DNorm::default();
let y = curve.sample(0.5);

Implementations

impl Curve2DNorm

pub fn new(y_first: f32, points: Vec<V2>, y_last: f32) -> Self

pub fn iter_points(&self) -> impl Iterator<Item = V2> + '_

pub fn len(&self) -> usize

pub fn sample(&self, x: f32) -> f32

Sample the curve at position x.

Returns the y-value at the given x position using linear interpolation. Input x is clamped to [0.0, 1.0].

pub fn add_point(&mut self, point: V2) -> Result<()>

pub fn remove_point_at(&mut self, index: usize) -> Result<()>

pub fn update_endpoint(&mut self, is_first: bool, y: f32)

pub fn update_point_y_norm(&mut self, index: usize, y: f32) -> Result<()>

pub fn update_point_norm( &mut self, index: usize, new_loc_norm: V2, ) -> Result<()>

Trait Implementations

impl Clone for Curve2DNorm

fn clone(&self) -> Curve2DNorm

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Curve2DNorm

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Curve2DNorm

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Curve2DNorm

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Curve2DNorm

fn eq(&self, other: &Curve2DNorm) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Curve2DNorm

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
