Struct nannou_laser::point::Point

#[repr(C)]
pub struct Point {
    pub position: Position,
    pub color: Rgb,
    pub weight: u32,
}

The point type used within the laser frame stream API.

The point represents the location to which the scanner should point and the colour that the scanner should be at this point.

If two consecutive points have two different colours, the color values will be linearly interpolated.

Fields

position: Position

The position of the point. -1 represents the minimum value along the axis and 1 represents the maximum.

color: Rgb

The color of the point.

weight: u32

The minimum number of extra times this point should be drawn.

0 is the default used for drawing sequences of smooth line segments.

Values greater than 0 are useful for accenting individual points.

Implementations

impl Point

pub const DEFAULT_LINE_POINT_WEIGHT: u32

The default weight for points used to draw lines.

pub fn new(position: Position, color: Rgb) -> Self

Create a Point at the given position with the given colour with a default weight.

pub fn with_weight(position: Position, color: Rgb, weight: u32) -> Self

The same as Point::new but allows for specifying the weight of the point.

pub fn centered_blank() -> Self

Create a blank point at [0, 0].

pub fn blanked(&self) -> Self

Returns a point with the same position as self but with a black (blank) color.

pub fn is_blank(&self) -> bool

Whether or not the point is blank.

A point is considered blank if the colour is black.

pub fn to_raw(&self) -> RawPoint

Converts to a single raw point with the same position and color.

pub fn to_raw_weighted(&self) -> impl Iterator<Item = RawPoint>

Converts to weight number of raw points with the same position and color.

Trait Implementations

impl AsRef<Point> for Point

fn as_ref(&self) -> &Point

Performs the conversion.

impl Clone for Point

fn clone(&self) -> Point

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Point

impl Debug for Point

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

Formats the value using the given formatter.

impl From<Point> for RawPoint

fn from(p: Point) -> Self

Performs the conversion.

impl Hash for Point

fn hash<H: Hasher>(&self, hasher: &mut H)

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl IsBlank for Point

fn is_blank(&self) -> bool

Whether or not the point is blank.

impl PartialEq<Point> for Point

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Position for Point

fn position(&self) -> [f32; 2]

The position of the point, where [-1.0, -1.0] is the bottom left and [1.0, 1.0] is the top right.

impl StructuralPartialEq for Point

impl Weight for Point

fn weight(&self) -> u32

The minimum number of extra times this point should be drawn.
