Class BloomSystem

bloomTextureView

• get bloomTextureView(): GPUTextureView

  The final bloom texture view to bind in the post-process pass. After renderPasses(), this contains the blurred bright regions. When bloom is disabled it is still a valid (black) texture.

  Returns GPUTextureView

constructor

• new BloomSystem(ctx: Context, options?: Partial<BloomOptions>): BloomSystem

  Creates a BloomSystem and builds all internal GPU pipelines.

  Parameters

  • ctx: Context

    Active context.

  • options: Partial<BloomOptions> = {}

    Initial bloom configuration.

  Returns BloomSystem

destroy

• destroy(): void

  Releases all GPU resources owned by the bloom system.

  Returns void

renderPasses

• renderPasses(ctx: Context, commandEncoder: GPUCommandEncoder): void

  Executes all bloom render passes (bright-pass + N×blur) into the ping-pong textures. Call this between the main render pass and the post-process pass.

  Parameters

  • ctx: Context

    Active context.

  • commandEncoder: GPUCommandEncoder

    Current frame command encoder.

  Returns void

resize

• resize(
      ctx: Context,
      width: number,
      height: number,
      sceneTextureView: GPUTextureView,
  ): void

  Reallocates bloom ping-pong textures to match the new canvas dimensions. Must be called whenever the canvas resizes.

  Parameters

  • ctx: Context

    Active context.

  • width: number

    New canvas pixel width.

  • height: number

    New canvas pixel height.

  • sceneTextureView: GPUTextureView

    The main scene color texture view (for the bright-pass bind group).

  Returns void
