F3D - fast and minimalist 3D viewer

By the F3D-APP Foundation.

F3D (pronounced `/fɛd/`) is a fast and minimalist 3D viewer desktop application. It supports many file formats, from digital content to scientific datasets, including glTF, USD, STL, STEP, PLY, OBJ, FBX, and Alembic. It can show animations, generate thumbnails, and provide many rendering and texturing options including real-time physically based rendering and raytracing.

It is fully controllable from the command line and supports configuration files. It supports interactive hotkeys, drag and drop, and integration into file managers.

F3D also contains libf3d, a simple library to render meshes, with a C++17 API and C, Python, Java, and JavaScript bindings.

See the gallery for more images, take a look at the changelog or go to the download page to download and install F3D!

You can even use F3D directly in your browser!

If you need any help or want to discuss with other F3D users and developers, head over to our Discord.

Installation

Install F3D from the download page, which lists the latest release packages and installation options for supported platforms. Once installed, the f3d command should be available from your terminal.

Quickstart

Open a file directly in F3D or from the command line by running:

f3d /path/to/file.ext

Optionally, append --output=/path/to/img.png to save the rendering into an image file.

See the quickstart guide for more information about getting started with F3D.

Many thanks to our sponsors for supporting F3D

Vision

As a minimalist 3D viewer F3D aims to:

• Support as many 3D file formats as possible
• Support many types of renderings (textures, edges, etc... ) and visualizations (meshes, volumic, point sprites)
• Support any and all use-cases dealing with 3D datasets
• Let any user easily and quickly view any model with good defaults
• Be as configurable as possible
• Be fully controllable from the command line and configuration file
• Be usable non-interactively
• Be as modular as possible to be built with a small number of dependencies

but there is no plan to:

• Provide a classic mouse-based UI, with menus and buttons
• Provide data processing tools
• Provide export feature

Contributing

F3D is a community-driven, inclusive and beginner-friendly project. We love to see how the project is growing thanks to the contributions from the community.
