3D Controller Overlay + (kurz 3dco+) wurde in der Version v1.0.0 veröffentlicht.

3dco+ ist ein Overlay-Tool, das Eingaben von Controllern, Tastatur und Maus in Echtzeit als individuelles 3D-Modell darstellt - nützlich für Streamer und Content-Creator, die ihre Eingaben ohne Kamera auf den Händen zeigen wollen.

Der Fork des Original-Tools von Larf bringt unter anderem eigenen 3D-Modell-Import (FBX, glTF, OBJ), Gyro-Unterstützung mit Drift-Korrektur und fertige Builds für Linux, Windows und macOS mit.

✨ What’s new in 1.0.0

This fork builds on the original 3D Controller Overlay by Larf. The + brings a massive set of improvements:

🖥️ Rendering & Customisation

• Custom model import via Assimp (FBX, glTF, OBJ, etc.) - assign meshes to controller parts directly in the app.
• Pivot-point editing - drag any mesh’s pivot in the 3D viewport instead of editing raw numbers.
• Per-part material alpha - make individual buttons transparent if you need to.
• Dual-highlight colors for axes (positive vs. negative) with adjustable deadzone.
• Touch-area visualisation - see exactly where the touchpad hit-box is on your mesh.
• Multi-touchpad support - up to 4 pads x 2 fingers each.

🎮 Input

• Keyboard & mouse overlays (system-wide) - works even when the app doesn’t have focus.
• Raw joystick fallback - if SDL doesn’t recognise your controller, you can still map it manually.
• Gyro & accelerometer - sensitivity, drift correction, and a configurable reset button combo.
• Manual mapping UI - bind any button, axis, or hat to any mesh, with inversion support.

🔧 Engineering

• Structured logging (spdlog) with an in-app log window.
• CMake build system + Docker cross-build scripts for reproducible packaging.
• AppImage, Windows .exe, and macOS universal .app builds via GitHub Actions.
• Embedded model library - the bundled models are packed into the binary, no separate assets folder to lose.
• Updated to SDL3 and latest Dear ImGui for better performance and bug fixes.
