Functions

byteSizeOfFormat

  • byteSizeOfFormat(context: Context, format: GLenum): number

  • Provides the size in bytes of certain WebGL format enumerator. Please note that some byte sizes might vary based on context attributes or the bound render, thus, DEPTH_COMPONENT and DEPTH_STENCIL are not covered by this function. This function does NOT cover data types that are usually on CPU side, not GPU, e.g., UNSIGNED_BYTE, UNSIGNED_SHORT_5_6_5, HALF_FLOAT, UNSIGNED_SHORT, FLOAT, etc. and will assert when provided with types.

    Parameters

    • context: Context

      The OpenGL context.

    • format: GLenum

      Format identifier of the target internal OpenGL data type.

    Returns number

    • The size in bytes of one type instance on the GPU.
