Struct pbrt::textures::constant::ConstantTexture

pub struct ConstantTexture<T> where
    T: Debug,  { /* fields omitted */ }

Implements trait Texture to return the given value.

Methods

impl<T> ConstantTexture<T> where
    T: Debug, 

pub fn new(value: T) -> ConstantTexture<T>

Create a new ConstantTexture with the given constant value.

Examples

use pbrt::core::spectrum::Spectrum;
use pbrt::core::texture::Texture;
use pbrt::textures::constant::ConstantTexture;

let t = ConstantTexture::new(10.);
assert_eq!(10., t.evaluate(&Default::default()));

let t = ConstantTexture::new(Spectrum::from_rgb([1., 0., 0.]));
assert_eq!(
    Spectrum::from_rgb([1., 0., 0.]),
    t.evaluate(&Default::default())
);

Trait Implementations

impl<T: Clone> Clone for ConstantTexture<T> where
    T: Debug, 

fn clone(&self) -> ConstantTexture<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for ConstantTexture<T> where
    T: Debug, 

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

Implements fmt that surfaces the relevant details for the ConstantTexture.

impl<T> Texture<T> for ConstantTexture<T> where
    T: Clone + Debug, 

fn evaluate(&self, _si: &SurfaceInteraction) -> T

Implements evaluate that just returns the same value for any SurfaceInteraction
