F3D is a 3D file viewer that is both free and open source. Available on Windows, Mac, and Linux, it offers a variety of formats such as glTF, STL, STEP, PLY, OBJ, FBX, and Alembic. F3D has a neat function of integrating into the Windows or Linux shell, and it can generate 3D thumbnails of 3D objects. Additionally, it can raytrace 3D models, which is its coolest feature. F3D is fully customizable, and you can create transparent images, raytraced, and denoised images, control the camera position, and HDRI environment mapping. The program can be run from the command line, and there are many features to make your 3D viewing experience great.
The F3D software is a 3D viewer that is known for its speed and minimalist design.
It can open various file formats, including digital content and scientific datasets like glTF, STL, STEP, PLY, OBJ, FBX, and Alembic. F3D has many features, such as the ability to display animations, support for thumbnails, and a range of rendering and texturing options, including real-time physically based rendering and raytracing.
It is flexible and can be controlled fully via the command line and configuration files, and it supports interactive hotkeys, drag and drop functionality and integration with file managers.
F3D also includes a simple library for rendering meshes, which has C++ and Python Bindings, with experimental Java and Javascript bindings.
The software is open source under the BSD-3 open source license hosted on GitHub. Additionally, there is a library for 3D model rendering that is part of the application.
