VTK and ImGui ( Setup / Build ) vs 2022 community

vtk_imgui.md

NOTES

Build VTK from src (cmake n Vs 2022)

i followed mostly this guide

• install cmake (latest)
• install visual studio 2022 community
• download vtk (latest), extract in src (like)
  • c:\vtk\src
  • c:\vtk\build (create empty dir)
• run cmake gui from start, give 2 above dirs
• run configure / generate
• run open solution (project) in visual studio
• set to Release and ALL_BUILD. build project

NOW TO INSTALL THE BUILD

• open cmake gui again, same settings
• config / generate again ( make sure, vtk install path is good)
• open solution(project)
• make INSTALL project(solution default)
• make sure, run as admin, so it can install
• don't forget to add vtk\bin dir to path.

to run example download any

• even after path, i got error
• so i have added that path in my project configuration (debugging)
• Deebugging >> Environment >> PATH=$(PATH);C:\Program Files (x86)\VTK\bin

ImGui in visual studio 2022 community

based on guide from here

0- copy imgui source to vendor subdir, in a new c++ windows empty project (template) 1- decide/pick between ( dx9,10,12,opengl etc) i.e i picked dx9 2- put imgui src in a subdir under 'vendor' and in project settings, add that path in vc++ directories >> likee >> $(ProjectDir)vendor\ImGui 3- connect directx 9 static lib (project linker settings ) 4- then in project, show all files, and select related .h and .cpp files, RMB and add to project. 5- write my cpp code in main file and run and it worked...

c++ , using msys2 (g++) in vscode (failed)

• Get MSYS2 from here
• install it, run it via msys2.exe
  • it opens it bash shell, run cmd
  • pacman -S --needed base-devel mingw-w64-ucrt-x86_64-toolchain
  • add this to user env
    • C:\msys64\ucrt64\bin
• run cpp file from code (run without debug)
  • pick g++ (g++.exe) as compiler
    • pick mingw64 as platform
    • pick g++ (g++.exe) as linker
  • run it
• notice tasks.json being added
  • edit tasks.json like

    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: g++.exe build active file",
