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.
