ColorGradingTexture

This represents a color grading texture. This acts as a lookup table LUT, useful during post process It can help converting any input color in a desired output one. This can then be used to create effects from sepia, black and white to sixties or futuristic rendering...

The only supported format is currently 3dl. More information on LUT: https://en.wikipedia.org/wiki/3D_lookup_table

Constructors

constructor

Find examples in Playground
  • Instantiates a ColorGradingTexture from the following parameters.

    Parameters

    • url: string

      The location of the color gradind data (currently only supporting 3dl)

    • scene: Scene

      The scene the texture will be used in

    Returns ColorGradingTexture

Properties

animations

Find examples in Playground
animations: Animation[]

Define the list of animation attached to the texture.

anisotropicFilteringLevel

Find examples in Playground
anisotropicFilteringLevel: number

With compliant hardware and browser (supporting anisotropic filtering) this defines the level of anisotropic filtering in the texture. The higher the better but the slower. This defaults to 4 as it seems to be the best tradeoff.

canRescale

Find examples in Playground
canRescale: boolean

Get if the texture can rescale.

coordinatesIndex

Find examples in Playground
coordinatesIndex: number

Define the UV chanel to use starting from 0 and defaulting to 0. This is part of the texture as textures usually maps to one uv set.

coordinatesMode

Find examples in Playground
coordinatesMode: number

How a texture is mapped.

Value Type Description
0 EXPLICIT_MODE
1 SPHERICAL_MODE
2 PLANAR_MODE
3 CUBIC_MODE

Find examples in Playground
delayLoadState: number

Define the current state of the loading sequence when in delayed load mode.

gammaSpace

Find examples in Playground
gammaSpace: boolean

Define if the texture contains data in gamma space (most of the png/jpg aside bump). HDR texture are usually stored in linear space. This only impacts the PBR and Background materials

getAlphaFromRGB

Find examples in Playground
getAlphaFromRGB: boolean

Defines if the alpha value should be determined via the rgb values. If true the luminance of the pixel might be used to find the corresponding alpha value.

hasAlpha

Find examples in Playground

Define if the texture is having a usable alpha value (can be use for transparency or glossiness for instance).

invertZ

Find examples in Playground
invertZ: boolean

Is Z inverted in the texture (useful in a cube texture).

is3D: boolean

Define if the texture is a 3d texture (webgl 2) or if false a 2d texture.

isBlocking

Find examples in Playground
isBlocking: boolean

Define if the texture is preventinga material to render or not. If not and the texture is not ready, the engine will use a default black texture instead.

Find examples in Playground
isCube: boolean

Define if the texture is a cube texture or if false a 2d texture.

isRGBD

Find examples in Playground
isRGBD: boolean

Gets whether or not the texture contains RGBD data.

isRenderTarget

Find examples in Playground
isRenderTarget: boolean

Define if the texture is a render target.

level

Find examples in Playground
level: number

Intensity or strength of the texture. It is commonly used by materials to fine tune the intensity of the texture

lodGenerationOffset

Find examples in Playground
lodGenerationOffset: number

With prefiltered texture, defined the offset used during the prefiltering steps.

lodGenerationScale

Find examples in Playground
lodGenerationScale: number

With prefiltered texture, defined the scale used during the prefiltering steps.

name

Find examples in Playground
name: string

Define the name of the texture.

onDispose

Find examples in Playground
onDispose: function

Callback triggered when the texture has been disposed. Kept for back compatibility, you can use the onDisposeObservable instead.

Type declaration

    • (): void
    • Returns void

onDisposeObservable

Find examples in Playground
onDisposeObservable: Observable<BaseTexture>

An event triggered when the texture is disposed.

sphericalPolynomial

Find examples in Playground
sphericalPolynomial: Nullable<SphericalPolynomial>

Get the polynomial representation of the texture data. This is mainly use as a fast way to recover IBL Diffuse irradiance data.

textureFormat

Find examples in Playground
textureFormat: number

Get the texture underlying format (RGB, RGBA...)

textureType

Find examples in Playground
textureType: number

Get the texture underlying type (INT, FLOAT...)

uid

Find examples in Playground
uid: string

Define the unique id of the texture in the scene.

url

Find examples in Playground
url: string

The texture URL.
