ImGuizmo

A collection of Dear ImGui widgets for 3D manipulation and more.

For API reference and usage examples, see the documentation.

Each widget is a standalone .h/.cpp pair that can be used independently. A unified static library containing all components is also available via the provided CMake build.

Manipulate view orientation with a single line of code.

A small library built on top of Dear ImGui that allows you to manipulate 4x4 float matrices (rotation, translation, and scale). Designed with the Immediate Mode philosophy in mind and has no additional dependencies.

A timeline sequencer for editing frame start/end ranges across multiple events.

A node graph editor with connections and a delegate system for custom rendering inside nodes.

A path editor widget for 2D vector geometry. Supports a pen tool, anchor and handle editing, open and closed paths, and host-provided transforms that compose with ImGuizmo object manipulation.

ImGuizmo can be installed via vcpkg:

vcpkg install imguizmo

See the vcpkg example for more details.

cmake -B build
cmake --build build --config Release

The CMake example fetches Dear ImGui and stb. It compiles Dear ImGui's upstream backends/imgui_impl_opengl3.cpp renderer, including its embedded OpenGL loader and dynamic font texture support, while retaining ImApp's native Windows, X11, and macOS window/input handling. No separate GL loader is required.

If building the example outside CMake, compile imgui_impl_opengl3.cpp from the same Dear ImGui checkout as the core sources and add backends to the include path. The legacy MinGW Makefile expects the Dear ImGui core sources in example and its backend source, header, and imgui_impl_opengl3_loader.h in example/backends.
