We need a virtual tour app for iOS (both iPad and iPhone compatible).
A virtual tour consists of one or more 3D Panoramas, linked with hotspots.
A Panorama is a rendered sphere mapped with an **equirectangular **?texture.
A hotspot is a coordinate in that image, marked with an icon, that when is tapped it gets you to another panorama. The texture size is going to be **4096x8192** pixels.
The panoramic viewer should support finger swipe rotation, as well as **compass/ device orientation** rotation. There should be an option to turn off the compass and navigate only by swipe. The viewer should also support zoom in/out.
The tours that are going to be displayed are going to be in **zip** format (with modified extension) and are going to contain all the panorama images in the tour, along with an XML/JSON file that defines the hotspots in each panorama, as well as the first panorama that is going to be shown.
The app should **register the file format**, so that it will be able to open these files from email attachments or itunes transfer.
The app will consist of an initial view that will be basically a list of panoramas that are loaded in the app, and another view with the panorama renderer.
The app is going to be a native OpanGl Es app, and not a container of HTML5.
Should you have any more questions, feel free to ask them.
Good luck!
