Stereoscopic images are hard to get right, and comfortable images are often only produced after repeated trial and error. The main difficulty is controlling the stereoscopic camera parameters so that the viewer does not experience eye strain or double images from excessive perceived depth. Additionally, for head tracked displays, the perceived objects can distort as the viewer moves to look aro...

This paper explicitly report on computer aided assembly animation of a tricycle for paraplegics who have difficulty in the use of lower limbs for mobility or driving.The development started with studying of existing tricycle and a case study of the recommended design standard for the features of vehicular cabs was taken. Analysis of the design requirements was made to determine all that would b...

The most common approach to animate models and determine their shape attributes in computer graphics is using skeletons. The skeleton and skinning weights can be either assigned manually or computed from an input mesh. This paper proposes the extraction of a skeleton and skinning weights from a mesh, describes how to store computed data in Collada 1.5 and use it for an animation. Firstly, the m...

Many real-time 3D graphics renderers represent each object as a collection of simple polygons. The complexity of this polygon structure is of practical relevance because it can manifestly a ect the performance of the graphics system. It is therefore commonplace to nd techniques to reduce the polygonal complexity of a model with the ultimate aim of improving the interactivity of the application....

BACKGROUND The present study contrasts the accuracy of different reconstructed models with distinctive segmentation methods performed by various experts. Seven research groups reconstructed nine 3D models of one human femur based on an acquired CT image using their own computational methods. As a reference model for accuracy assessment, a 3D surface scan of the human femur was created using an ...

We present an interactive system to create 3D models of objects of interest in their natural cluttered environments. A typical setting for 3D modeling of an object of interest involves capturing images from multiple views in a multi-camera studio with a mono-color screen or structured lighting. This is a tedious process and cannot be applied to a variety of objects. Moreover, general scene reco...

Immersive virtual environments and natural 3D user interfaces have shown great potential in the field of architecture, especially for exploration, presentation and review of designs. In this paper we propose an augmented virtual studio environment for architectural exploration based on a mixed-reality head-mounted display environment. The proposed system supports (1) real walking through large ...

This paper describes a passive stereo system for capturing the 3D geometry of a face in a single-shot under standard light sources. The system is low-cost and easy to deploy. Results are submillimeter accurate and commensurate with those from state-ofthe-art systems based on active lighting, and the models meet the quality requirements of a demanding domain like the movie industry. Recovered mo...
