Struct ColorGradingLut 

pub struct ColorGradingLut { /* private fields */ }

Color grading look up table (LUT). Color grading is used to modify color space of the rendered frame; it maps one color space to another. It is widely used effect in games, you’ve probably noticed either “warmness” or “coldness” in colors in various scenes in games - this is achieved by color grading.

Implementations

impl ColorGradingLut

pub const UNWRAPPED_LUT: &'static str = "unwrapped_lut"

impl ColorGradingLut

pub async fn new( unwrapped_lut: TextureResource, ) -> Result<Self, ColorGradingLutCreationError>

Creates 3D look-up texture from 2D strip.

Input Texture Requirements

Width: 1024px Height: 16px Pixel Format: RGB8/RGBA8

Usage

Typical usage would be:

async fn create_lut(resource_manager: ResourceManager) -> ColorGradingLut {
    ColorGradingLut::new(resource_manager.request::<Texture>(
        "your_lut.jpg",
    ))
    .await
    .unwrap()
}

Then pass LUT to either CameraBuilder or to camera instance, and don’t forget to enable color grading.

pub fn unwrapped_lut(&self) -> TextureResource

Returns color grading unwrapped look-up table. This is initial texture that was used to create the look-up table.

pub fn lut(&self) -> TextureResource

Returns 3D color grading look-up table ready for use on GPU.

pub fn lut_ref(&self) -> &TextureResource

Returns 3D color grading look-up table by ref ready for use on GPU.

Trait Implementations

impl Clone for ColorGradingLut

fn clone(&self) -> ColorGradingLut

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColorGradingLut

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

Formats the value using the given formatter.

impl Default for ColorGradingLut

fn default() -> ColorGradingLut

Returns the “default value” for a type.

impl PartialEq for ColorGradingLut

fn eq(&self, other: &ColorGradingLut) -> 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 Reflect for ColorGradingLut

fn assembly_name(&self) -> &'static str

Returns a parent assembly name of the type that implements this trait. WARNING: You should use proc-macro (#[derive(Reflect)]) to ensure that this method will return correct assembly name. In other words - there’s no guarantee, that any implementation other than proc-macro will return a correct name of the assembly. Alternatively, you can use env!("CARGO_PKG_NAME") as an implementation.

fn type_assembly_name() -> &'static str
