Class SquareDataTextureArray<TArray, TLayerProxy>

constructor

• new SquareDataTextureArray<
      TArray extends TypedArrayType,
      TLayerProxy extends
          SquareDataTextureLayerProxy<TArray> = SquareDataTextureLayerProxy<
          TArray,
      >,
  >(
      device: GraphicsDevice,
      params: ISquareDataTextureArrayParams<TArray>,
  ): SquareDataTextureArray<TArray, TLayerProxy>

  Type Parameters

  • TArray extends TypedArrayType

    CPU buffer element type

  • TLayerProxy extends SquareDataTextureLayerProxy<TArray> = SquareDataTextureLayerProxy<TArray>

    per-layer writer proxy (defaults to SquareDataTextureLayerProxy)

  Parameters

  • device: GraphicsDevice
  • params: ISquareDataTextureArrayParams<TArray>

  Returns SquareDataTextureArray<TArray, TLayerProxy>

maxUpdateCalls

partialUpdate

capacity

• get capacity(): number

  Maximum number of instances that the texture can hold.

  Returns number

channels

• get channels(): TChannelSize

  Number of channels per pixel.

  Returns TChannelSize

data

• get data(): TArray

  Returns TArray

layerProxies

• get layerProxies(): TLayerProxy[]

  Returns TLayerProxy[]

layers

• get layers(): number

  Returns number

layerViews

• get layerViews(): TArray[]

  Data for each layer.

  Returns TArray[]

pixelsPerInstance

• get pixelsPerInstance(): number

  Number of pixels per instance.

  Returns number

texture

• get texture(): Texture

  Texture.

  Returns Texture

destroy

• destroy(): void

  Returns void

enqueueDataUpdate

• enqueueDataUpdate(index: number, inData: TArray, offset?: number): void

  Parameters

  • index: number
  • inData: TArray
  • offset: number = 0

  Returns void

enqueueDataUpdateLayer

• enqueueDataUpdateLayer(
      layer: number,
      index: number,
      inData: TArray,
      offset?: number,
  ): void

  Parameters

  • layer: number

    Layer index.

  • index: number

    Index of the instance.

  • inData: TArray

    Data to update.

  • offset: number = 0

    Offset in the data.

  Returns void

enqueueUpdate

• enqueueUpdate(index: number): void

  Parameters

  • index: number

  Returns void

enqueueUpdateLayer

• enqueueUpdateLayer(layer: number, index: number): void

  Update data for specific layer.

  Parameters

  • layer: number

    Layer index.

  • index: number

    Index of the instance.

  Returns void

getLayer

• getLayer(layer: number): TLayerProxy

  Parameters

  • layer: number

  Returns TLayerProxy

getLayerData

• getLayerData(layer: number): TArray

  Parameters

  • layer: number

  Returns TArray

resize

• resize(count: number, layers?: number): void

  Resize instance capacity. Optionally change layer count in the same call. Changing layers recreates the GPU texture (arrayLength is immutable).

  Parameters

  • count: number
  • layers: number = ...

  Returns void

resizeLayers

• resizeLayers(layers: number): void

  Resize texture-array depth (sampler2DArray layers). Recreates the GPU texture; existing layer proxies for kept indices are reused.

  Parameters

  • layers: number

  Returns void

update

• update(): void

  Update the texture on the GPU.

  Returns void

upload

• upload(): void

  Upload the texture to the GPU.

  Returns void
