初始化 Texture2DArray

Question

我正在尝试通过以下方式创建和初始化 2D 纹理数组：

D3D11_TEXTURE2D_DESC desc{};
desc.ArraySize = 10; // there should be 10 textures
desc.BindFlags = D3D11_BIND_SHADER_RESOURCE | D3D11_BIND_UNORDERED_ACCESS;
desc.Usage = D3D11_USAGE_DEFAULT;
desc.Format = DXGI_FORMAT_R32G32B32A32_FLOAT;
desc.Width = 256;
desc.Height = 1;
desc.MipLevels = 1;
desc.SampleDesc.Count = 1;
desc.CPUAccessFlags = 0;

D3D11_SUBRESOURCE_DATA subresourceData{};
subresourceData.pSysMem = data.data(); // data is a vector of 2560 elements of type XMVECTOR
subresourceData.SysMemPitch = 256 * sizeof(XMVECTOR);
subresourceData.SysMemSlicePitch = 256 * sizeof(XMVECTOR);

Microsoft::WRL::ComPtr<ID3D11Texture2D> m_texture = nullptr;

m_device->CreateTexture2D(&desc, &subresourceData, &m_texture);

问题是我在NULL中调用CreateTexture2D和m_texture时遇到错误Access violation reading location 0xFFFFFFFFFFFFFFFF 。 当我没有传递初始化数据时，问题没有发生：

m_device->CreateTexture2D(&desc, nullptr, &m_texture);

如何初始化纹理数组？

Answer 1

问题已解决：对于纹理数组，您必须在CreateTexture2D function 中传递一个D3D11_SUBRESOURCE_DATA数组。
