d3d | 3D -- Some utils for 3D object detection | Machine Learning library

I am trying to remove horizontal lines from my daughter's drawings, but can't get it quite right.

The approach I am following is creating a mask with horizontal lines (https://stackoverflow.com/a/57410471/1873521) and then removing that mask from the original (https://docs.opencv.org/3.3.1/df/d3d/tutorial_py_inpainting.html).

As you can see in the pics below, this only partially removes the horizontal lines, and also creates a few distortions, as some of the original drawing horizontal-ish lines also end up in the mask.

Any help improving this approach would be greatly appreciated!

I use JavaFX with Java 8 and i set this properties before launching my app
System.setProperty("prism.forceGPU","true");
System.setProperty("prism.order","d3d,sw");
The verbose mode for prism gives me this :

I'm working on a d3d application and i would like to compile my .hlsl shaders during to build using cmake. I have no idea where to start.

this is my current CMakeLists.txt

I'm trying to build my first HoloLens app using Unity. I imported the MRTK and its features. I also connected the HoloLens through USB. As soon as I press "Build and Run" it provides 3 errors. My build settings for Universal Windows Platform are the following:

• Target Device: HoloLens,
• Architect: ARM (I also tried ARM64),
• Build Type: D3D Project,
• Target SDK Version: Latest Installed,
• Minimum Platform Version: (all the versions give the same error),
• Visual Studio Version: Latest Installed,
• Build and Run on: USB Device,
• Build Configuration: Release.

Regardless of the build settings, the following errors appear as soon as I press the "Build and Run":

I have a D3D11 Texture2d with the format DXGI_FORMAT_R10G10B10A2_UNORM and want to convert this into a D3D11 Texture2d with a DXGI_FORMAT_R32G32B32A32_FLOAT or DXGI_FORMAT_R8G8B8A8_UINT format, as those textures can only be imported into CUDA.

For performance reasons I want this to fully operate on the GPU. I read some threads suggesting, I should set the second texture as a render target and render the first texture onto it or to convert the texture via a pixel shader.

But as I don't know a lot about D3D I wasn't able to do it like that. In an ideal world I would be able to do this stuff without setting up a whole rendering pipeline including IA, VS, etc...

Does anyone maybe has an example of this or any hints? Thanks in advance!

I'm trying to use Desktop Capture API in c++ project.

Here is initialisation of frame pool:

I have built my app with JavaFX 11 and now I need to distribute it. I have chosen to distribute it in two ways: cross-platform fat-jar (I know, I know, it is discouraged, but that is not the point) and platform specific image created with jlink.

I am building on Linux Mint 20.1. I am using Maven and creating runtime image with javafx-maven-plugin. I have JDKs for both platforms on my Linux machine and pointed to the corresponding jmods folder in pom.xml.

The built fat-jar works on both Linux and Windows where both have installed the latest Java SDK (11.0.12).

The image for Linux also works without problems.

However, the image for Windows does not run and the output of -Dprism.verbose=true is this:

I want make a Direct2D GUI that will run on a DLL and will render with the Direct3D of the application that I inject into it.

I know that I can simply use ID2D1Factory::CreateDxgiSurfaceRenderTarget to make a DXGI surface and use it as d2d render target, but this require enabling the flag D3D11_CREATE_DEVICE_BGRA_SUPPORT on Direct3D's device.

The problem is that the application creates its device without enabling this flag and, for this reason, ID2D1Factory::CreateDxgiSurfaceRenderTarget fails.

I am trying to find a other way to draw on the application window (externally or inside window's render target) that also works if that window is in full-screen.

I tried these alternatives so far:

1. Create a d2d render target with ID2D1Factory::CreateDCRenderTarget. This worked, but the part I rendered was blinking/flashing (show and hide very fast in loop). I also called ID2D1DCRenderTarget::BindDC before ID2D1RenderTarget::BeginDraw, but it just blinks but a bit less, so I still had the same issue.

2. Create a new window that will always be on the top of every other window and render there with d2d but, if the application goes into full-screen, then this window does not show on screen.

3. Create a second D3D device with enabled the D3D11_CREATE_DEVICE_BGRA_SUPPORT flag and share an ID3D11Texture2D resource between the device of the window and my own, but I wasn't able to make it work... There are not a lot of examples on how to do it. The idea was to create a 2nd device, draw with d2d on that device and then sync the 2 D3D devices – I followed this example (with direct11).

4. Create a D2D device and share the data of d2d device with d3d device; but, when I call ID2D1Factory1::CreateDevice to create the device it fails because the D3D device is created without enabling the D3D11_CREATE_DEVICE_BGRA_SUPPORT flag. I started with this example.

I've heard of hardware overlay but it works only on some graphics cards and I think I will have problems with this https://docs.microsoft.com/el-gr/windows/win32/medfound/hardware-overlay-support.

I am currently at a dead end; I don't know what to do. Does anyone have any idea that may help me?

Maybe is there any way to draw on screen and work even if a window is in full-screen?

I am using SharpDX to basically render browser (chromium) output buffer on directX process.

Process is relatively simple, I intercept CEF buffer (by overriding OnPaint method) and write that to a texture2D.

Code is relatively simple:
