I'm trying to create a Texture2D array with CPU write access. In detail, the code I'm using looks like this:
D3D10_TEXTURE2D_DESC texDesc;
texDesc.Width = 32;
texDesc.Height = 32;
texDesc.MipLevels = 1;
texDesc.ArraySize = 2;
texDesc.SampleDesc.Count = 1;
texDesc.SampleDesc.Quality = 0;
texDesc.Usage = D3D10_USAGE_DYNAMIC;
texDesc.CPUAccessFlags = CPU_ACCESS_WRITE;
texDesc.Format = DXGI_FORMAT_R32G32B32_FLOAT;
texDesc.BindFlags = D3D10_BIND_SHADER_RESOURCE;
texDesc.MiscFlags = 0;
ID3D10Texture2D* texture2D;
CHECK_SUCCESS(device->CreateTexture2D(&texDesc, NULL, &texture2D));
This, however, fails with E_INVALIDARG. Creating a 3D texture with the same dimensions (ie 32x32x2) and parameters works well, but is not desired in this case.
Does anyone know why this setup would not be valid?
You need to provide an array of D3D11_SUBRESOURCE_DATA of length texDesc.ArraySize as input for the second parameter of CreateTexture2D().
For more help see this example.

I am trying to make a desktop recorder, but all i get, is black screen, i have no clue why at all.
I tried with dx9, but same thing when i use backbuffer, front buffer method does work, and it can capture the frames correctly, but it's too slow (33ms per frame, and all because of GetFrontBuffer).
So i decided to try with dx11, there are no errors from return, no errors when creating swapchain and device, everything is fine, and in fact the frames are captured(i measure the time and fps, and something is going on), but they are all black, like it's not coming from the desktop, but from somewhere else.
This is the capture method
if(contains_errors()){return;}
m_swap_chain->GetBuffer(0, __uuidof(ID3D11Resource), (void**)&m_back_buffer_ptr);
return_if_null(m_back_buffer_ptr);
HRESULT hr = m_back_buffer_ptr->QueryInterface(__uuidof(ID3D11Resource), (void**)&m_back_buffer_data);
return_if_failed(hr);
hr = m_swap_chain->GetDevice(__uuidof(ID3D11Device), (void**)&m_device);
return_if_failed(hr);
hr = m_swap_chain->GetDesc(&m_desc);
return_if_failed(hr);
ID3D11Texture2D* texture = nullptr;
hr = m_device->CreateTexture2D(&m_tex_desc, 0, &texture);
return_if_failed(hr);
ID3D11DeviceContext* context = nullptr;
m_device->GetImmediateContext(&context);
return_if_null(context);
context->CopyResource(texture, m_back_buffer_data);
D3D11_MAPPED_SUBRESOURCE map_subres = {0, 0, 0};
hr = context->Map(texture, 0, D3D11_MAP_READ, 0, &map_subres);
return_if_failed(hr);
if(m_current_frame == 0)
{
m_current_frame = new BYTE[map_subres.DepthPitch];
}
memcpy(m_current_frame, map_subres.pData, map_subres.DepthPitch);
texture->Release();
m_device->Release();
This is the texture desc setup
ZeroMemory(&m_tex_desc, sizeof(m_tex_desc));
m_tex_desc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;
m_tex_desc.Width = m_desc.BufferDesc.Width;
m_tex_desc.Height = m_desc.BufferDesc.Height;
m_tex_desc.MipLevels = 1;
m_tex_desc.ArraySize = 1;
m_tex_desc.SampleDesc.Count = 1;
m_tex_desc.Usage = D3D11_USAGE_STAGING;
m_tex_desc.BindFlags = 0;
m_tex_desc.CPUAccessFlags = D3D11_CPU_ACCESS_READ;
m_tex_desc.MiscFlags = 0;
This is swapchain desc
m_desc.BufferDesc.Width = 1366;
m_desc.BufferDesc.Height = 768;
m_desc.BufferDesc.RefreshRate.Numerator = 1;
m_desc.BufferDesc.RefreshRate.Denominator = 60;

m_desc.BufferCount = 1;

m_desc.Windowed = true;

I look up basically all the resources i could, but i could not find any info why it does work, but the image is all black. I was thinking maybe there is something up with the display, but no, i took the raw data, and display the value, and all the pixel or whatever it was is, was exactly 0, which is black color.
In the "m_desc.OutputWindow = (HWND)m_dx_win->winId();" i tried to also use GetDesktopWindow(), but it doesn't change anything, in fact i got some warnings instead.
i am pretty newbie on directx.
and i am stumbling with handling resource.
Okay First, i created texture that i can read/write in GPU, and it worked well.
And now, as you can check in my code, i wanted to read this texture in CPU as well(reading from application side), so i edited the usage from USAGE_DEFAULT to USAGE_DYNAMIC.
Microsoft::WRL::ComPtr<ID3D11Texture2D> outputTexture;
D3D11_TEXTURE2D_DESC outputTex_desc;
outputTex_desc.Format = DXGI_FORMAT_R32_FLOAT;
outputTex_desc.Width = 3;
outputTex_desc.Height = 3;
outputTex_desc.MipLevels = 1;
outputTex_desc.ArraySize = 1;
outputTex_desc.BindFlags = D3D11_BIND_UNORDERED_ACCESS |
D3D11_BIND_SHADER_RESOURCE;
outputTex_desc.SampleDesc.Count = msCount;
outputTex_desc.SampleDesc.Quality = msQuality;
outputTex_desc.Usage = D3D11_USAGE_DYNAMIC;
outputTex_desc.CPUAccessFlags = D3D11_CPU_ACCESS_READ;
outputTex_desc.MiscFlags = 0;
// CREATE 'TEXTURE'
device->CreateTexture2D( // FAIL HERE !!!
&outputTex_desc,
nullptr,
outputTexture.GetAddressOf());
// CREATE 'SRV'
...
// CREATE 'UAV'
...
and it starts failing exactly when it executes the 'device->CreateTexture2D()'
any advice would be amazing.
The first two steps in debugging any Direct3D 11 program is:
Make sure you are checking every HRESULT for either success (SUCCEEDED macro) or failure (FAILED macro). If it is safe to ignore the return value at runtime, then the function returns void. See ThrowIfFailed.
Enable the Direct3D debug device and look for debug output (a.k.a. use D3D11_CREATE_DEVICE_DEBUG in your Debug configuration).
If you enable the Direct3D debug device, you'll get detailed information on why the API returns failure codes in many cases.
If you did that, you'd see the error for this code:
D3D11 ERROR: ID3D11Device::CreateTexture2D: A D3D11_USAGE_DYNAMIC Resource
may only have the D3D11_CPU_ACCESS_WRITE CPUAccessFlags set.
[ STATE_CREATION ERROR #98: CREATETEXTURE2D_INVALIDCPUACCESSFLAGS]
In order to READ it on the CPU, you must copy to a D3D11_USAGE_STAGING Resource first. For example source code on doing that, see the ScreenGrab code from DirectX Tool Kit.
You don't mention what your msCount or msQuality values are here. I assumed 1, and 0 respectively. If you use any other values, you'll get:
D3D11 ERROR: ID3D11Device::CreateTexture2D: Multisampling is not supported
with the D3D11_BIND_UNORDERED_ACCESS BindFlag. SampleDesc.Count must be 1
and SampleDesc.Quality must be 0.
[ STATE_CREATION ERROR #99: CREATETEXTURE2D_INVALIDBINDFLAGS]
In order to access a texture from cpu (read mode), you need you create a separate staging texture, then copy your texture into it.
These are the flags for the gpu only texture (please note I force sample count to 1, as UAV access is not allowed for multisampled textures)
D3D11_TEXTURE2D_DESC gpuTexDesc;
gpuTexDesc.Format = DXGI_FORMAT_R32_FLOAT;
gpuTexDesc.Width = 3;
gpuTexDesc.Height = 3;
gpuTexDesc.MipLevels = 1;
gpuTexDesc.ArraySize = 1;
gpuTexDesc.BindFlags = D3D11_BIND_UNORDERED_ACCESS |
D3D11_BIND_SHADER_RESOURCE;
gpuTexDesc.SampleDesc.Count = 1;
gpuTexDesc.SampleDesc.Quality = 0;
gpuTexDesc.Usage = D3D11_USAGE_DEFAULT;
gpuTexDesc.CPUAccessFlags = D3D11_CPU_ACCESS_NONE;
gpuTexDesc.MiscFlags = 0;
Then you create a second texture for reading
D3D11_TEXTURE2D_DESC readTexDesc;
readTexDesc.Format = DXGI_FORMAT_R32_FLOAT;
readTexDesc.Width = 3;
readTexDesc.Height = 3;
readTexDesc.MipLevels = 1;
readTexDesc.ArraySize = 1;
readTexDesc.BindFlags = 0; //No bind flags allowed for staging
readTexDesc.SampleDesc.Count = 1;
readTexDesc.SampleDesc.Quality = 0;
readTexDesc.Usage = D3D11_USAGE_STAGING; //need staging flag for read
readTexDesc.CPUAccessFlags = D3D11_CPU_ACCESS_READ;
readTexDesc.MiscFlags = 0;
then you can use CopyResource:
deviceContext->CopyResource(readTex, gpuTex);
Once done, you can finally access texture data for reading using Map
D3D11_MAPPED_SUBRESOURCE MappedResource;
deviceContext->Map(readTex, 0, D3D11_MAP_READ, 0, &MappedResource);
MappedResource will give you access to data in cpu, once you done processing, don't forget to Unmap the resource.
deviceContext->Unmap(readTex, 0);
I'm puzzled why this isn't working.
I'm trying to add texture data to each of the cube textures faces. For some reason, only the first(+x) works. The MSDN documentation is quite sparse, but it looks like this should do the trick:
// mip-level 0 data
// R8G8B8A8 texture
uint32_t sizeWidth = textureWidth * sizeof(uint8_t) * 4;
if (isCubeTexture)
{
for (uint32_t index = 0; index < gCubemapNumTextures; ++index)
{
const uint32_t subResourceID = D3D11CalcSubresource(0, index, 1);
context->UpdateSubresource(mTexture, subResourceID, NULL, &textureData.at(sizeWidth * textureHeight * index), sizeWidth, 0);
}
}
When debugging and looking at the faces its all just black except the first face, which seems to load fine. So obivously I am doing somerhing wrong, how do you properly upload cubetexture data to all the faces?
EDIT: follow parameters used to create the texture:
D3D11_TEXTURE2D_DESC textureDesc;
ZeroMemory(&textureDesc, sizeof(D3D11_TEXTURE2D_DESC));
textureDesc.Width = textureWidth;
textureDesc.Height = textureHeight;
textureDesc.ArraySize = isCubeTexture ? gCubemapNumTextures : 1;
if (isSRGB)
textureDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM_SRGB;
else
textureDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;
textureDesc.SampleDesc.Count = 1;
textureDesc.Usage = D3D11_USAGE_DEFAULT;
textureDesc.BindFlags = D3D11_BIND_RENDER_TARGET | D3D11_BIND_SHADER_RESOURCE;
textureDesc.MiscFlags = D3D11_RESOURCE_MISC_GENERATE_MIPS;
if (isCubeTexture)
textureDesc.MiscFlags |= D3D11_RESOURCE_MISC_TEXTURECUBE;
DXCALL(device->CreateTexture2D(&textureDesc, NULL, &mTexture));
Then after uploading the data I generate mip chain like this:
context->GenerateMips(mShaderResourceView);
And again, it works fine but only for the first (+x) face.
You create the texture with "0" mip levels by virtue of zero'ing out the texture description. Zero means "full mip chain please", which means more than 1 mip (unless your texture is 1x1).
Your arguments to D3D11CalcSubresource has a third argument of '1', suggesting only one mip, which appears not to be true. Be sure to pass in the correct number of mips to this helper function or it won't calculate the correct subresource index.
You can get the mip count by calling GetDesc() after the texture has been created.
ok i tried everything at this point and I'm really lost....

depthStencilViewDesc.Texture2D.MipSlice = 0;
mDevice->CreateDepthStencilView(depthStencilTexture, &depthStencilViewDesc, &mDepthStencilView);
mDeviceContext->OMSetDepthStencilState(mDepthStencilState, 1);
and then afterwards i call
mDeviceContext->OMSetRenderTargets(1, &mTargetView, mDepthStencilView);
obviously i clean before every frame
mDeviceContext->ClearRenderTargetView(mTargetView, D3DXCOLOR(0.0f, 0.0f, 0.0f, 1.0f));
mDeviceContext->ClearDepthStencilView(mDepthStencilView, D3D11_CLEAR_DEPTH, 1.0f, 0 );
and still it just keeps the last pixel drawn with no testing....

PS i've checked the rasterizer and it is correctly drawing only the front faces
any help anyone?
Check your HRESULTs - the call to CreateTexture2D is almost certainly failing because you have specified CPU_ACCESS flags on a DEFAULT texture. Since you never check any errors or pointers, this just propagates NULL to all your depth objects, effectively disabling depth testing.
You can also catch errors like this by enabling D3D debug layers, by adding D3D11_CREATE_DEVICE_DEBUG to the flags on D3D11CreateDevice. If you had done this, you would see the following debug spew:
D3D11 ERROR: ID3D11Device::CreateTexture2D: A D3D11_USAGE_DEFAULT
Resource cannot have any CPUAccessFlags set. The following
CPUAccessFlags bits cannot be set in this case: D3D11_CPU_ACCESS_READ

I have one WDDM user mode display driver for DX9. Now I would like to dump the
render target's back buffer to a bmp file. Since the render target resource is
not lockable, I have to create a resource from system buffer and bitblt from the
render target to the system buffer and then save the system buffer to the bmp
file. However, calling the bitblt always return the error code E_FAIL. I also
tried to call the pfnCaptureToSysMem which also returned the same error code.
Anything wrong here?

You are on the right track, but I think you can use the DirectX functions for this.
In order to copy the render target from video memory to system memory you should use the IDirect3DDevice9::GetRenderTargetData() function.
This function requires that the destination surface is an offscreen plain surface created with pool D3DPOOL_SYSTEMMEM. This surface also must have the same dimensions as the render target (no stretching allowed). Use IDirect3DDevice9::CreateOffscreenPlain() to create this surface.
Then this surface can be locked and the color data can be accessed by the CPU.
