Lumin ImGui Framework

Lumin is a C++20 Dear ImGui menu framework with a Direct3D 11 demo application. It includes a styled login flow, sidebar navigation, animated tab transitions, theme presets, glass overlays, toast notifications, and reusable widgets such as checkboxes, sliders, dropdowns, color pickers, keybinds, text fields, and search filters.

Requirements

• Windows 10 or Windows 11
• Visual Studio 2022 with the Desktop development with C++ workload
• Windows 10/11 SDK installed through Visual Studio

ImGui, FreeType headers/library, stb_image, and UI font assets are vendored in this repository. The project uses Direct3D headers and libraries from the installed Windows SDK.

Build

Visual Studio

1. Open framework.sln.
2. Select Release | x64.
3. Build the solution.

The demo executable is generated at:

thirdparty\imgui\examples\example_win32_directx11\Release\lumin_ui_demo.exe

Command Line

From a Visual Studio Developer PowerShell:

msbuild framework.sln /p:Configuration=Release /p:Platform=x64 /m

Demo Login

The demo login accepts demo by default. This is only a sample UI gate, not an authentication or licensing system. Change license_key_matches in framework/gui.cpp before using the flow in a real product.
