Vizerra
Vizerra is a software platform for viewing 3D models which provides its user with integrated additional content, such as video guides. Currently available 3D models are used for demonstration, advertising and educational purposes. Project Overview. The project title has its origins in Latin and combines three words: "visio" (”vision, image”), "erro" (”roam”) and "terra" (“earth”). It was chosen because Vizerra project began as a platform for virtual travel. At the moment Vizerra is primarily a library of virtual 3D copies of real sites. These include monasteries, temples, squares and monuments of ancient cultures, such as Machu Picchu, Prague’s  Old Town Square, Angkor Wat and others. Client Application.
