Browse GZ, RAR and ZIP archives and view 3D content from a variety of popular data formats right on your iPhone, iPad or iPod Touch. View 3D data attached to E-mail messages, download from websites or online cloud storage or transfer via iTunes document exchange or from the Files app. 3Dskope natively supports 3DS, ASE, OBJ, PLY, and STL formats. Additional data formats are available via 3Dskope Importer extensions (see below). 3Dskope also handles some bitmap formats not supported by iOS (e.g. DDS, TIFF, TGA). Other document types (AR content, PDF's, photos, movies, office doc's, etc...) are passed to iOS for preview generation. Thus, 3Dskope is an advanced, high quality 3D viewer with additional general-purpose content viewing capabilities. 3Dskope lets you play animations embedded in 3DS or ASE files (mono- or stereoscopic), lets you toggle light sources and gives you an overview of the elements that comprise the scene (cameras, lights, materials, meshes, groups). In addition to polygonal mesh geometry 3Dskope can import NURBS curves and surfaces from OBJ files. Using 3Dskope's Magic Crosshair™ you can measure coordinates, distances, areas and volumes. In addition you can use the clip tool to display and animate cross-sectional views. You can customize the UI for left-hand or right-hand operation. Also, you can select from a number of background patterns, gradients and color schemes or define your own look. Additional capabilities are available via In-App Purchase extensions: - 3Dskope Professional lets you load scene textures, provides extended visualization modes, and lets you render your scene in high resolution with transparent background. On supported devices an additional spatial image is generated when rendering in side-by-side stereo mode. - 3Dskope Explorer provides a new and intuitive way to view the properties of your scene’s cameras, lights, materials, nodes, animation tracks and animation keys. In addition you can explore individual meshes in a separate 3D view. - 3Dskope Exporter lets you save your scene to various popular data formats (3DS, OBJ/MTL, PLY, and STL are currently available). Free trial exporters are included for evaluation. These have full functionality but the trial exporter's output can only be opened with 3Dskope and only on the same device. This way you can test the exporter before buying the unrestricted version via In-App purchase. - 3Dskope Importer provides support for additional data formats. Static preview generation is available for free. Again, this lets you test before you buy the full functionality for a specific data format via In-App purchase. AC3D is the first additional data format provided by a 3Dskope Importer extension. For a detailed app description view the 3Dskope Quick Start Guide on our website. There are also some short tutorial videos on YouTube. Just search for "3Dskope". Please contact Seselmo Support if you have questions about 3Dskope or if you want to leave feedback.

visualOS is an infinite canvas for people who think visually. It is an infinite canvas for notes, folders, images, to-do’s and sketches. It works fully offline and saves to real files in a folder on your device. YOUR DATA IS A FOLDER YOU CAN OPEN Connect any folder on your disk and visualOS mirrors your canvas into it — every folder on the canvas is a real folder, every document a Markdown file, every image an image. Put the folder in iCloud or Dropbox and it syncs through your cloud, not ours. If you ever leave, everything stays readable. Forever. OFFLINE ISN'T A MODE. IT'S THE ARCHITECTURE. On a flight, on the train, in a studio with no signal — visualOS doesn’t care. There is no server to reach, so there is no spinner, no sync wheel, no login wall. Your canvas opens instantly because everything is already here. BOARDS WITHIN BOARDS Any board can hold more boards. A project becomes a world: moodboards inside client boards inside your studio. Drag elements into a board to file them away; breadcrumbs keep you oriented; a double-tap takes you deeper. NO ACCOUNT. NO SUBSCRIPTION. Open it and work. There's nothing to sign up for, nothing to verify, nothing to cancel. Pay once and it's yours forever — one purchase unlocks every Apple device. FREE IN THE BROWSER BUT THE APP GOES FURTHER Try visualOS free in your browser at visualos.app. When you're ready for it everywhere, the app adds what a browser can't: true offline access on the train or a plane, native pan-and-zoom gestures, Apple Pencil drawing, and your boards saved as real files that sync across iPhone, iPad and Mac through your own iCloud. EVERYTHING ELSE • Notes & rich text • Long-form documents stored as plain Markdown • Interactive to-do lists on the canvas • Images & PDFs — drag, paste or drop them in • Freehand drawing • Magnetic arrows that snap and bend • Search every board at once • Groups, locking and a snap grid Your ideas. Your files. ABOUT US As creatives, we’ve always relied on visual canvas tools to organize our thoughts, plan projects, and make sense of ideas. But one thing kept bothering us: our files and knowledge were always tied to cloud-based services. We wanted the freedom to access everything offline, without worrying about losing our work or giving up our privacy. So why can’t our own files on our device be visualized in the same intuitive way? And that’s how the idea for visualOS was born: a visual representation of your internal folder structure — offline, private, and secure. Your data stays on your device, where it belongs. We’re Sarah and Gerald, a husband-and-wife team who have been living, loving, and building things together for more than 20 years. Creating visualOS has been a ton of fun and thanks to AI we were able to push it further than we initially imagined. Now we’d love to hear what you think. If visualOS helps you work a little more creatively or makes your files easier to navigate, we’d be grateful if you shared it with others.
