🏃 Animation control
cut.mp4
A new animation bar have been added that let you see the key frames and manipulate the time with your mouse.

🤖 Android improvements
The Android application have been completely reworked. Many rendering issues have been fixed, and new widgets have been implemented, including animation control.

🎥 Video export
simplescreenrecorder-2026-10-21_08.51.50.mp4
It's now possible to export animation into a video stream. The stream can be sent over the network or just piped into ffmpeg to generate a video file:
f3d animated_file.glb --output-video=- --resolution=600,600 | ffmpeg -i - out.mp4

⚙️ FreeCAD reader
FreeCAD file (.FCStd) can now be opened with F3D. Parts visibility can be toggle in the scene hierarchy widget (press H)

🌐 HTML custom element
Visualizing your asset online is just as easy as adding this to your HTML file:
<f3d-viewer id="viewer" src="https://f3d.app/data/f3d.glb" />
Almost no additional javascript code required, see examples

⚗️ New Alembic Features!
F3D is now able to read Xform animations and Curves from the alembic format!
Image
🇨 C bindings
The libf3d now have C bindings for complete intercompatibility
with other languages:
https://f3d.app/docs/next/libf3d/LANGUAGE_BINDINGS#c
Here is a quick prototype of Julia binding that uses the libf3d C bindings:
https://github.com/joa-quim/F3D.jl
🔃 Complete examples
We now have libf3d examples for:
- C bindings
- Python bindings
- Java bindings
- C++ bindings with multiple usecase
- FLTK
- Qt6
- QML
See how easy it is to create your own app using the libf3d!
// Load static/native plugins
f3d::engine::autoloadPlugins();
// Create a native-window engine
f3d::engine eng = f3d::engine::create();
// Modify options using the struct API
f3d::options& opt = eng.getOptions();
opt.render.grid.enable = true;
opt.render.show_edges = true;
// UI overlays: axis + some HUD
opt.ui.axis = true;
opt.ui.fps = true;
opt.ui.animation_progress = true;
opt.ui.filename = true;
// FXAA + tone mapping
opt.render.effect.antialiasing.enable = true;
opt.render.effect.antialiasing.mode = "fxaa";

// Add a model to the scene
eng.getScene().add(file);
}
catch (const std::exception& e)
{
std::cerr << e.what() << '\n';
}
// Start interaction loop
eng.getInteractor().start();
