ITensorStaticsNative.CreateFromD3D12Resource method

  • Article

Creates a tensor object (TensorFloat, TensorInt32Bit) from a user-specified ID3D12Resource.

HRESULT CreateFromD3D12Resource(
    ID3D12Resource *value,
    [size_is(shapeCount)] __int64 *shape,
    int shapeCount,
    [out] IUnknown ** result);

Parameters

Name Type Description
value ID3D12Resource* The ID3D12Resource from which to create the tensor.
shape __int64* The shape of the tensor.
shapeCount int The number of dimensions of the tensor.
result IUnknown** The resulting tensor.

Returns

HRESULT The result of the operation.

Examples

TensorFloat SoftwareBitmapToDX12Tensor(SoftwareBitmap softwareBitmap)
{
    // ...

    // GPU tensorize
    com_ptr<ITensorStaticsNative> tensorfactory = get_activation_factory<TensorFloat, ITensorStaticsNative>();
    com_ptr<::IUnknown> spUnkTensor;
    TensorFloat input1imagetensor(nullptr);
    int64_t shapes[4] = { 1,3, softwareBitmap.PixelWidth(), softwareBitmap.PixelHeight() };
    CHECK_HRESULT(tensorfactory->CreateFromD3D12Resource(pGPUResource.get(), shapes, 4, spUnkTensor.put()));
    spUnkTensor.try_as(input1imagetensor);

    // ...
