Class WgCompAddShader

constructor

• new WgCompAddShader(context: WgContext, input: WgBuffer<Uint32Array>, addend: WgBuffer<Uint32Array> | number | Uint32Array, blockSize?: undefined | number, output?: WgBuffer<Uint32Array>, outputOffset?: undefined | number): WgCompAddShader

• Parameters

  • context: WgContext

    The WebGPU context

  • input: WgBuffer<Uint32Array>

    The INPUT to which the ADDEND will be added

  • addend: WgBuffer<Uint32Array> | number | Uint32Array

    The ADDEND. This can have multiple forms: - A scalar value: Every value in the INPUT will be incremented by this value - Multiple values: The values of INPUT will be increment by the values passed here in a block-wise manner. This will depend on the value passed on 'blockSize'. See the description of that parameter for more details

  • Optional blockSize: undefined | number

    The size of each addition block. A block is a section of the INPUT data that will be incremented by the same value contained in the ADDEND buffer. Example: - The 1st n=blockSize elements (i.e. range [0,blockSize)) of INPUT will be incremented by the 1st ADDEND value - The next n=blockSize elements (i.e. range [blockSize,2blockSize)) of INPUT will be incremented by the 2nd ADDEND value - The next n=blockSize elements (i.e. range [2blockSize,3*blockSize)) of INPUT will be incremented by the 3rd ADDEND value - And so on... If 'blockSize' is undefined, it will be automatically calculated to span the entire INPUT range as uniformly as possible: blockSize = ceil( len(INPUT) / len(ADDEND) ); where len() gives the number of elements of INPUT and ADDEND

  • Optional output: WgBuffer<Uint32Array>

    If provided, the output buffer of this shader (useful for debugging)

  • Optional outputOffset: undefined | number

    If provided, the offset of the output buffer (useful for debugging)

  Returns WgCompAddShader
