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

getMsaaRenderBuffer

getMsaaRenderBuffer(source: TextureSource): WebGLRenderbuffer
The multisampled renderbuffer an antialiased texture is drawn into, made on first use, with its storage at the texture's current size. It belongs to the texture, so every render target over the texture shares its samples, and it is deleted with the texture's GL texture.
Parameters
- source: TextureSource
  a colour attachment of an antialiased target, or its depth/stencil texture
Returns WebGLRenderbuffer
its multisampled renderbuffer

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
