    Class BatcherAbstract Advanced

    A batcher is used to batch together objects with the same texture. It is an abstract class that must be extended. see DefaultBatcher for an example.

    Properties

    attributeBuffer: ViewableBuffer

    The buffer containing attribute data for all elements in the batch.

    attributeSize: number

    The current size of the attribute data in the batch.

    batches: Batch[] = []

    An array of all batches created during the current rendering process.

    batchIndex: number = 0

    The current index of the batch being processed.

    dirty: boolean = true

    Indicates whether the batch data has been modified and needs updating.

    elementSize: number

    The total number of elements currently in the batch.

    elementStart: number

    The starting index of elements in the current batch.

    geometry: Geometry

    The geometry used by this batcher. Must be implemented by subclasses.

    indexBuffer: IndexBufferArray

    The buffer containing index data for all elements in the batch.

    indexSize: number

    The current size of the index data in the batch.

    maxTextures: number

    The maximum number of textures per batch.

    name: string

    The name of the batcher. Must be implemented by subclasses.

    shader: Shader

    The shader used by this batcher. Must be implemented by subclasses. this can be shared by multiple batchers of the same type.

    uid: number = ...

    unique id for this batcher

    defaultOptions: Partial<BatcherOptions> = ...

    Methods

    • Returns void

    • breaks the batcher. This happens when a batch gets too big, or we need to switch to a different type of rendering (a filter for example)

      Parameters

      Returns void

    • Returns void

    • Resizes the attribute buffer to the given size (1 = 1 float32)

      Parameters

      • size: number

        the size in vertices to ensure (not bytes!)

      Returns void

    • Resizes the index buffer to the given size (1 = 1 float32)

      Parameters

      • size: number

        the size in vertices to ensure (not bytes!)

      Returns void

    • Packs the attributes of a BatchableMeshElement into the provided views. Must be implemented by subclasses.

      Parameters

      • element: BatchableMeshElement

        The BatchableMeshElement to pack.

      • float32View: Float32Array

        The Float32Array view to pack into.

      • uint32View: Uint32Array

        The Uint32Array view to pack into.

      • index: number

        The starting index in the views.

      • textureId: number

        The texture ID to use.

      Returns void

    • Packs the attributes of a BatchableQuadElement into the provided views. Must be implemented by subclasses.

      Parameters

      • element: BatchableQuadElement

        The BatchableQuadElement to pack.

      • float32View: Float32Array

        The Float32Array view to pack into.

      • uint32View: Uint32Array

        The Uint32Array view to pack into.

      • index: number

        The starting index in the views.

      • textureId: number

        The texture ID to use.

      Returns void

    • Parameters

      Returns void
