3D Viewer Online vs Marmoset Viewer

3D Viewer Online is a browser service for sharing, inspecting and reviewing 3D models. Its 3D Player and APIs can embed models in websites, catalogues and other applications. The viewer provides rotation, panning, zooming, preset views and measurement tools for checking geometry and dimensions. Users can share browser links, while teams add comments, markups and attached datasheets or supporting documents. Access depends on each model’s sharing settings. Listed formats include STEP, IGES, GLTF, 3MF, STL, OBJ, DWG and DXF; DWG and DXF do not support 3D solids. Embedding is available through external links or iframes. The REST API accepts uploads and returns a viewer URL and model ID, with token access and rate limits discussed with the company. The WebGL viewer is described for recent browsers on PCs, tablets and smartphones. The free Regular plan allows ten models and 50 MB files. Premium is $10/month and Business $25/month, both billed monthly.

Marmoset Viewer is a physically based WebGL viewer for sharing interactive 3D presentations on the web. Scenes are created in Marmoset Toolbag and exported as optimized .mview packages to host or embed. Viewer supports animated scenes, refractive materials, shadowed fog, and shadow catcher objects. Developers can embed packages using a JavaScript library and embed utility; packages can also be uploaded to ArtStation, and a third-party WordPress plugin is available for uploads and embedding. A free standalone desktop app opens .mview files locally and is downloadable separately from Toolbag. The maker lists Windows, OS X, iOS, and Android support, but says Android support is less robust than Windows, OS X, and iOS. Global illumination, screen-space reflections, and ambient occlusion are not supported. Because models and textures must be sent to the browser for rendering, the maker says robust copy protection is essentially impossible. The standalone Viewer app is free, and Viewer is included with Toolbag versions 2.07 and newer. The listed format is .mview; measurement tools and annotation or markup are not available.
