Yali Tzamisi, a 17th century monument located in Chania, Crete, has been photographed appropriately by three separate student groups, one for the building's envelope, one for the building's interior space and one for the surroundings of the monument. Different levels of detail and various file formats have been documented according to their scope of use, before the three models were merged into one unified 3D scene.Virtual3Dreconstructionpoint clouds10.1109/DigitalHeritage.2015.7413838
