Mobile UX matters a lot to me, so I tried four 3D model sites on my phone and focused on controls, loading, and guidance. Online 3D Viewer: The cleanest, most intuitive interface. It opens nearly 20 3D formats, and the manual clearly explains how to import and export. Convert3D: Of the four I tested, it's the only one that lets you change the background color. It can also generate 3D models from images. On my phone I hit a "device performance limit" message. Sketchfab: Best for browsing a huge library of models from other users. ModelViewer: Has AR, and you can see it experimenting with interaction. On my phone it needs polish, and when something fails it should tell users what to do next. What do you think?   submitted by   /u/onholdlab   to   r/3Dprinting [link]   [comments]
