Struct TransferFunction2DRegion 

pub struct TransferFunction2DRegion {
    pub scalar_range: [f64; 2],
    pub gradient_range: [f64; 2],
    pub rgba: [f64; 4],
}

An axis-aligned region in (scalar, gradient) space.

Regions are composited in insertion order using source-over alpha blending.

Fields

scalar_range: [f64; 2]

Inclusive scalar range covered by the region.

gradient_range: [f64; 2]

Inclusive gradient-magnitude range covered by the region.

rgba: [f64; 4]

RGBA colour produced when the sample falls inside the region.

Implementations

impl TransferFunction2DRegion

pub fn new( scalar_range: [f64; 2], gradient_range: [f64; 2], rgba: [f64; 4], ) -> Self

Create a new region.

pub fn contains(&self, scalar: f64, gradient: f64) -> bool

true if (scalar, gradient) lies inside the region.

Trait Implementations

impl Clone for TransferFunction2DRegion

fn clone(&self) -> TransferFunction2DRegion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TransferFunction2DRegion

impl Debug for TransferFunction2DRegion

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

Formats the value using the given formatter.

impl PartialEq for TransferFunction2DRegion

fn eq(&self, other: &TransferFunction2DRegion) -> 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.
