DearImGUI Sample

General Information#

Dear ImGui is a fast, minimalistic, and highly portable immediate-mode GUI library primarily used for creating in-game and real-time development tools. It's designed to be simple to integrate into existing applications and is especially popular in the game development, graphics, and visualization communities.

Rather than creating traditional GUI layouts, Dear ImGui allows developers to quickly build dynamic interfaces - perfect for debugging tools, editors, data visualizations, and real-time control panels. It focuses on responsiveness and ease of use, making it ideal for prototyping and tools where performance and simplicity matter.

How to Run the Sample#

Prerequisites#

  • UNIGINE SDK Browser (latest version)
  • UNIGINE SDK Community or Community PRO edition
  • Visual Studio 2022 (recommended)
  • GitHub access to clone the repository.

Step-by-Step Guide#

The C++ sample uses Dear ImGui library v.1.81 (https://github.com/ocornut/imgui/releases/tag/v1.81)

Starting the Dear ImGui C++ sample requires you to perform the following steps:

  1. Clone or download the sample from the UNIGINE Git repository
  2. Open SDK Browser and make sure you have the latest version
  3. Add the sample project to SDK Browser:

    • Go to the My Projects tab
    • Click Add Existing then select the *.project file located in the cloned sample folder, and click Import Project

  4. Repair the project

    • After importing, you'll see a Repair warning - this is expected, as only essential files are stored in the Git repository. SDK Browser will restore the rest

    • Click Repair to let SDK Browser restore the required files
    • When the configuration window opens, click Configure Project without making any changes
      Notice
      This sample is currently released for UNIGINE SDK Community or Community PRO editions only. If you do not have a Community edition of the latest SDK, you should add it via the SDKs tab (this edition is free).
  5. Open the project in your IDE

    • Launch the recommended Visual Studio 2022 (other C++ IDE with CMake support can be used as well)
    • If everything is set up correctly, the CMakeLists.txt file will be highlighted in bold in the Solution Explorer window, indicating that the project is ready to build
  6. Build and Run the project

    • Click Build to compile the project and then Run to launch the application.

If you're still having trouble running the application, revisit the steps above to ensure nothing was skipped. If you encounter CMake issues in Visual Studio, try rebuilding the project by right-clicking on it in the Visual Studio 2022, selecting Delete Cache and Reconfigure and then Build again.

The information on this page is valid for UNIGINE 2.20 SDK.
