Constructors

constructor

new GlTextureSystem(renderer: WebGLRenderer): GlTextureSystem
Parameters
- renderer: WebGLRenderer
Returns GlTextureSystem

Accessors

managedTextures

get managedTextures(): readonly TextureSource<any>[]

Returns readonly TextureSource<any>[]

Deprecated
since 8.15.0

Methods

bind

bind(texture: BindableTexture, location?: number): void
Parameters
- texture: BindableTexture
- location: number = 0
Returns void

bindSource

bindSource(source: TextureSource, location?: number): void
Parameters
- source: TextureSource
- location: number = 0
Returns void

destroy

destroy(): void

Generic destroy methods to be overridden by the subclass

Returns void

Implementation of System.destroy

generateCanvas

generateCanvas(texture: Texture): ICanvas
Parameters
- texture: Texture
Returns ICanvas

Implementation of CanvasGenerator.generateCanvas

getGlSource

getGlSource(source: TextureSource): GlTexture
Parameters
- source: TextureSource
Returns GlTexture

getPixels

getPixels(texture: Texture): GetPixelsOutput
Parameters
- texture: Texture
Returns GetPixelsOutput

Implementation of CanvasGenerator.getPixels

initSource

initSource(source: TextureSource): void
Initializes a texture source, if it has already been initialized nothing will happen.
Parameters
- source: TextureSource
  The texture source to initialize.
Returns void
The initialized texture source.

resetState

resetState(): void

Returns void

unbind

unbind(texture: BindableTexture): void
Parameters
- texture: BindableTexture
Returns void

unbindIntegerTextures

unbindIntegerTextures(location: number): void
Binds the empty texture over every integer texture on unit location and above

WebGL fails a draw when a float sampler's unit holds an integer texture, even if the shader never samples it. Call this after binding a batch's textures when the shader declares more samplers than the batch binds.
Parameters
- location: number
  The first texture unit to check.
Returns void
