Free high-performance secure and easy-to-use online viewer for 360° spherical panoramas. It works directly from the page and leverages the power of WebGL engine built into all modern browsers. No additional plug-ins required. Simply drag and drop the panoramic image with an equirectangular projection directly into the viewer rectangle on a page, and it will instantly prepare and show you a ready-made panorama, which you can rotate, zoom in and out, go in full screen. The panorama viewer software runs only in your browser and works offline (server independent), the images you use remain completely confidential.
Unique standalone image viewer oriented to work with reference images. Has built-in always on top mode and the ability to display multiple images at once. Its main purpose is to keep reference images constantly observable. Even if you run another program in maximized window mode, the reference images will still be visible. Its third distinctive feature is the capability to download images directly from web browsers by simple drag and drop. It also can handle images from clipboard in both directions (copy "from" and paste "to"). Paste an image from clipboard to RefShelf and you already have saved reference for further usage. RefShelf can really make life easier for the most CG artists and not just for them either!
