Gallery: Post your screenshots / code here (PART 26)

We are very happy to use Dear ImGui in our Viewer application (desktop and web), the interactive post-processing tool part of our structural analysis SOFiSTiK suite: https://www.sofistik.com/

source code avaible at https://github.com/FCFlenkchy/FCAE_VPN and very nice library

This is my WIP vibe game engine https://github.com/sindney/fury3d, picked up with vibe coding from a 9 year old code base.

Grinding Gear Games is still using ImGUI for development. This time it's for Path of Exile 2. https://youtu.be/XDEJLOHcdWw?si=R0622BnIk3jVuDxz&t=205

I wanted a "wheel" widget for a personal project. That evidently didnt seem to have been made before, so with some inspiration from imgui-knobs i created imgui-wheels:

Map any Dear ImGui control to a MIDI CC

imMidiMapper

Here is another widget I have publicized from my personal project. This time it's some fancy sliders that, in my application, are hooked up to a physical console. I just wanted the sliders to have more "pizzazz" (sorry Omar, the default ones look fine, I'm just needy). With that, I have made these sliders available in the same way that the wheels are.

Also, here is an image of the previously mentioned personal project.

Imgui works perfectly for my custom stage lighting application, and the application has been used at a festival called "Frederiksund Festival" in Denmark. Although I do need to fix some minor bugs and also the obvious text clipping.

Smeltrix - work in progress A C++ runtime with a Dear ImGui frontend

Main UI

Multi-instance UI

OSD, Ring UI, and Main UI running simultaneously as independent frontend instances.

Context selection is handled through GImGui = MyImGuiTLS. Each instance has its own Renderer, Window, and WndProc, and runs in parallel.

Dear ImGui itself is unmodified. Smeltrix handles the multi-instance and multithreaded parts.

Rendering APIs can be switched per instance at runtime. OpenGL, Vulkan, DX11, and DX12 instances can run at the same time.

Scheduled services can be monitored and controlled at runtime: cycle time, execution time, priority, pause/resume, and termination.

WebRemoteImgui: C++ library and example that brings Dear ImGui to the web. It executes all application logic on the server and streams the UI to any modern web browser using WebGL, while piping user interactions back in real-time. Features per-user sessions, making it ideal for remote monitoring, headless server dashboards, and cloud-based C++ tools.

Introduce ImGuiApplication.cpp, a library & C++ helper class for creating standalone Dear ImGui applications. It handles backend-related logics in the box, and developers only need to inherits ImGuiApplication class, and implement 3 essential interfaces. This makes developing applications much easier.

ImGuiApplication.cpp has been used in Manifold, my audio batch processor aiming at game audio pre-processing.

By the way, Manifold also includes lots of tricks for Dear ImGui.
