When building CS/IS-PBVR in Windows environment, Visual Studio 2022 is used. If you do not have it installed, download it from Microsoft's Website and launch the Visual Studio Installer. Next, select Install Visual Studio 2022 and check the following components:

• Select "Desktop development with C++" from "Workload".
• Select the following from the "Individual Components" section:
  • Windows 11 SDK
  • C++ ATL for latest v143 build tools (x86 and x64)
  • C++ CMake Tools for Windows

After selecting the components, click the "Install" button at the bottom right to start the installation. When the installation is complete, confirm that "x64 Native Tools Prompt for VS 2022" can be launched.

If you want to visualize .fbx format files in a client program, you need to install FBXSDK library. The steps are shown below.

• Select Download SDK for Windows from the Website and download fbx2XXXXX_fbxsdk_vs2022_win.exe.
• Run the fbx2XXXXX_fbxsdk_vs2022_win.exe and follow the installer to complete the installation.

If you want to visualize .3ds format files in a client program, you need to install the Assimp library. The steps are shown below.

• Download and extract the source code from the Website.

• Move to assimp-5.0.0¥ in the "x64 Native Tools Command Prompt for VS 2022" and execute the following command.

  cmake -G "Visual Studio 17 2022"
  MSBuild Assimp.sln /t:clean; rebuild /p:Configuration=Release; Platoform="x64"
  MSBuild Assimp.sln /t:clean; rebuild /p:Configuration=Debug; Platoform="x64"
  

• After the build is completed, confirm that (assimp-vc143-mt.lib/assimp-vc143-mtd.lib) is generated in assimp-5.0.0\lib(Release/Debug) and set the following environment variables.

  variable	value
  Path	< BASE_DIR>¥assimp-5.0.0¥bin¥Release
  Path	< BASE_DIR>\assimp-5.0.0\bin\Debug

If you want to display a visualization screen on an HMD from the client program using OpenXR, you need to install the SteamVR, ImGui library and OpenXR-SDK. Below are the installation steps.

To run PBVR using OpenXR, utilize the OpenXR runtime provided by Steam’s SteamVR. For instructions on installing SteamVR, refer to the WebSite. Ensure you have completed the setup procedures for your specific HMD.

Below are instructions for configuring the SteamVR OpenXR runtime

1. Start SteamVR, open the menu from the icon at the top, and select “Settings.”

1. In the SteamVR settings, select OpenXR. If “Current OpenXR Runtime” is not set to “SteamVR,” click the “Set SteamVR as OpenXR Runtime” button. If a User Account Control prompt appears, grant permission.

1. Confirm that it is set to “SteamVR.”

• Clone the source code from theWebSite

• Open “x64 Native Tools Command Prompt for VS 2022,” navigate to the imgui directory, and run the following commands

  cd imgui
  git checkout v1.91.0
  mkdir include
  cd include
  mkdir imgui
  cd imgui
  xcopy "..\..\*.h" .
  xcopy "..\..\*.cpp" .
  xcopy "..\..\backends\imgui_impl_opengl3*" .
  

• Make sure the directory structure is as follows

  <BASE_DIR>
  └─lib
    └─imgui
      ├─.github
      ├─backends
      ├─docs
      ├─examples
      ├─include
      │  └─imgui
      │    ├─imconfig.h

      │    ├─imstb_textedit.h
      │    └─imstb_truetype.h
      └─misc
  

• Set the environment variable as follows

  variable	value
  KVS_IMGUI_DIR	<BASE_DIR>¥lib¥IMGUI

• Clone the source code from the WebSite

• Open “x64 Native Tools Command Prompt for VS 2022,” navigate to the OpenXR-SDK directory, and run the following commands

  git checkout release-1.0.34
  mkdir build
  cd build
  cmake .. -G "Visual Studio 17 2022" -A x64 -D DYNAMIC_LOADER=ON
  MSBuild OPENXR.sln /t:clean;rebuild /p:Configuration=Release;Platoform="x64"
  MSBuild OPENXR.sln /t:clean;rebuild /p:Configuration=Debug;Platoform="x64"
  cd ..
  mkdir bin
  mkdir lib
  xcopy  "build\src\loader\Release\openxr_loader.dll" bin
  xcopy  "build\src\loader\Release\openxr_loader.lib" lib
  

• Set the environment variable as follows

  variable	value
  KVS_OPENXR_DIR	<BASE_DIR>¥lib¥OpenXR
