Interactive walkthrough are a realistic representation of properties that allow the user to know them more closely digitally. By means of 3D realistic models you can visit environments, which are physically distant, and achieve an immersive experience. These interactive walkthrough provide freedom of entirely being explored; something that photos and videos do not offer. They are also available for multiple platforms such as touch screens, and mobile devices (See Development for Multiple Platforms).  

See example: Virtual Tour for web
