Direct3D is part of Microsoft's DirectX application programming interface (API), which performs 3d graphics rendering in games, simulations etc. Direct3d11 is the 11th version of DirectX API released with DirectX 11.

Direct3D is used to render three dimensional graphics in applications where performance is important, such as games. Direct3D also allows applications to run fullscreen instead of embedded in a window, though they can still run in a window if programmed for that feature. Direct3D uses hardware acceleration if it is available on the graphics card, allowing for hardware acceleration of the entire 3D rendering pipeline or even only partial acceleration. Direct3D exposes the advanced graphics capabilities of 3D graphics hardware, including z-buffering, anti-aliasing, alpha blending, mipmapping, atmospheric effects, and perspective-correct texture mapping. Integration with other DirectX technologies enables Direct3D to deliver such features as video mapping, hardware 3D rendering in 2D overlay planes, and even sprites, providing the use of 2D and 3D graphics in interactive media titles.

Do I need CreateSharedHandle to pass a ID3D11Texture2D to another thread?

As the title says: do I need to use CreateSharedHandle to pass a ID3D11Texture2D generated in a thread to another thread in the same process? My use case is that each thread would use the texture with its own device created on the same adapter.

Direct2D command lists + multithreading

I'm researching options to offload D2D work from a render thread to a worker thread. The D2D worker thread would be used to generate textures (i.e., drawing to DXGI surface owned by the render thread's D3D context). The textures that get generated…

Converting RGBA data between DXGI formats

I need to convert ID3D11Texture2D texture of type DXGI_FORMAT_R32G32B32A32_TYPELESS to a texture of type DXGI_FORMAT_B8G8R8A8_TYPELESS (or any other 32-bit RGBA type) efficiently. Basically reducing 128 bits per pixel texture to 32 bits per pixel.…

Direct3D11 renders only lines, and in weird order

I have reduced a previous rending problem to a core where I am stuck. I have a vertex buffer, consisting of 4 vertices, arranged in a plane (labeled 0 to 3): 1. .2 0. .3 and an according index buffer {0,1,2,3,0}. Now, when I render with…
