How to Render DirectX view port in ImGui Window inside Dockspace

[sparkskapil]

I am trying to make an engine with DirectX 9 and ImGui.
Can anyone help me how to create a viewport window for my scene with imgui dockspace.

Render your viewport into a texture and render your texture using ImGui::Image().

@rokups Thanks for the reply. I have seen some tutorials to do this with OpenGL.
I am new to rendering, can you suggest some resources to implement this with DirectX9.
I have tried searching but couldn't find any tutorial or blog/post.

The google search you are looking for is "directx9 render offscreen surface". The primary API is this one: https://docs.microsoft.com/en-us/windows/win32/direct3d9/id3dxrendertosurface

Maybe we should amend this page
https://github.com/ocornut/imgui/wiki/Image-Loading-and-Displaying-Examples

With some basic keyboard/references for each graphics API ?
