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

Master your designs with CorelDRAW Graphics Suite
Free, full-featured 3D creation suite
Inkscape is an open-source vector graphics editor similar to Adobe Illustrator, Corel Draw, Freehand, or Xara X. What sets Inkscape apart is its use of Scalable Vector Graphics (SVG), an open XML-based W3C standard, as the native format. In contrast to raster (bitmap) graphics editors such as Photoshop or Gimp, Inkscape stores its graphics in a vector format. Vector graphics is a resolution-independent description of the actual shapes and objects that you see in the image. A rasterization engine uses this information to determine how to plot each line and curve at any resolution or zoom level. Contrast that to bitmap (raster) graphics which is always bound to a specific resolution and stores an image as a grid of pixels. Inkscape can import and display bitmap images, too. An imported bitmap becomes yet another object in your vector graphics, and you can do with it everything you can do to other kinds of objects (move, transform, clip, etc.) While Inkscape does not have all the features of the leading vector editors, the latest versions provide for a large portion of basic vector graphics editing capabilities. People report successfully using Inkscape in a lot of very different projects (web graphics, technical diagrams, icons, creative art, logos, maps).
