3DVT (or 3D virtual tourism) refers to the releastic 3D geovisualisation and navigation of virtual reality environments for purposes of exploring physical places in space and time without physically traveling there. 3DVT invokes a virtual tour that employs usage of 3D models in addition to 2D panoramic images, a sequence of hyperlinked still or video images, and/or image-based models of the real location and multimedia support elements such as sound effects, music, narration, and text. As opposed to actual tourism, 3DVT is accessed on a smartphone or computer (typically over the Internet). It does not require travel, but ideally, 3DVT viewing evokes an experience of moving through the represented 3D space.
