Aspose.3D Viewer vs F3D

Aspose.3D Viewer is a free browser-based tool for viewing 3D documents without installing specialized software. Upload a file by dragging it into the drop area, selecting it, or entering a file URL. Its interactive viewer lets users inspect content from different perspectives, and users can download the original file afterward. Supported formats include 3DS, 3MF, AMF, DAE, DXF, FBX, glTF, GLB, JT, OBJ, PLY, PDF, RVM, STL, U3D, VRML, Maya, Blender, OpenUSD, and IFC. The browser-based viewer works on Windows, Linux, macOS, Android, and iOS. Uploaded files are processed on Aspose servers using Aspose APIs and deleted after 24 hours; viewer and download links stop working then. Developers can consult Aspose.3D documentation to implement the viewing feature programmatically. Aspose lists a free plan and a Premium plan at $4 a month, billed as one payment of 48USD. Business pricing is custom and not listed.

F3D is free software for viewing 3D data, browsing models, and generating renderings. It supports lighting and materials for realistic rendering, animations with GPU-accelerated skinning for character rigs, and visualization tasks such as CAD, Gaussian splatting, volume rendering, and scientific work. Its supported formats include VTK, STL, DICOM, STEP, OBJ, glTF, FBX, USD, IFC, and Gaussian splat files, among many others. Packages are available for Windows, macOS, Linux, and Android, and a browser viewer can open or accept dropped files and provides rendering and display controls. Developers can use a Python package, a beta JavaScript/WebAssembly package, or the libf3d C++ library with Python and Java bindings. F3D is distributed under the BSD 3-Clause License. Some capabilities have specific limits: FBX PBR materials and Alembic materials are unsupported, while Gaussian splatting requires OpenGL 4.3, which macOS does not support. Documentation also says volume rendering and HDRI need a decent GPU. Plugins can vary by package.
