2D-3D Consistent Virtual Environment

3D Interaction in Virtual Environment

Any Pair of 2D Curves Is Consistent with a 3D

Symmetry has been shown to be a very effective a priori constraint in solving a 3D shape recovery problem. Symmetry is useful in 3D recovery because it is a form of redundancy. There are, however, some fundamental limits to the effectiveness of symmetry. Specifically, given two arbitrary curves in a single 2D image, one can always find a 3D mirror-symmetric interpretation of these curves under ...

Automatic Object Modeling for 3D Virtual Environment

3D object modeling is an important issue in creation of virtual environment. This paper presents an automatic modeling approach for construction of curved object models. Our approach is based on the use of multiple images and superquadric modeling primitives. 3D model is generated from the contours on orthographic planes of images taken from known viewpoints, and represented with a set of super...

A 3D Virtual Environment for Social Telepresence

We examine OnLive Traveler as a case study. Traveler is a clientserver application allowing real-time synchronous communication between individuals over the Internet. The Traveler client interface presents the user with a shared virtual 3D world, in which participants are represented by avatars. The primary mode of communication is through multi-point, full duplex voice, managed by the server. ...

3D panoramic imaging for virtual environment construction

The project is concerned with the development of algorithms for the creation of photo-realistic 3D virtual environments, overcoming problems in mosaicing, colour and lighting changes, correspondence search speed and correspondence errors due to lack of surface texture. A number of related new algorithms have been investigated for image stitching, content based colour correction and efficient 3D...
