abstract: Existing image-based virtual reality applications allow users to view image-based 3D virtual environment in a more interactive manner. User could "walkthrough"; looks left, right, up and down and even zoom into objects in these virtual worlds ofimages. However what the user sees during a "zoom in" is just a close-up view of the same image which was taken from a distant. Thus, this does not give the user an accurate view of the object from the actual distance. In this paper, a simple technique for zooming in an object in a virtual scene is presented. The technique is based on the 'hotspot' concept in existing application. Instead of navigation between two different locations, the hotspots are used to focus into an object in the scene. For each object, several hotspots are created. A different picture is taken for each hotspot. Each consecutive hotspot created will take the user closer to the object. This will provide the user with a correct of view of the object based on his proximity to the object. Implementation issues and the relevance of this technique in potential application areas are highlighted. © 2009 WASET.ORG.
