OpenGL is a commonly used modeling tool in the virtual scene modeling. However, OpenGL graphics library does not provide advanced modeling commands, in this case, it is difficult to create complicated scene models and the models which it created are less realistic. The professional three-dimensional modeling software has strong modeling capabilities, modeling vivid, but it can not meet the interoperability...
Virtual reaLity technology is one of new technologies involving multitudinous knowledge. Based on the virtual reaLity, the construction of complex three dimension (3D) CAD model and the way of reading are introduced. Taken VIRTOOLS as the platform, the processing of complex model and the dynamic interaction of the whole model with virtual environment are elaborated. With the example, the reaLization...
Virtual reality is a kind of comprehensive calculator sketch technique, multimedia technique, sensor technique, man-machine alternating technique, network technique, stereoscopic manifestation technique and imitate true technique etc. variety science technique get up of new technique of calculator realm. This system is a virtual scene lay out system at the integral whole of travel extensively and...
This paper proposes an extended COLLADA-based File Format to support various attributes of realistic objects for Virtual Reality (VR) applications. VR applications provide the user with virtual objects represented as 3D CG. To provide realistic virtual objects in a VR application, the developer of the VR application has to define many attributes of the corresponding real objects besides their 3D geometry...
This paper proposes a surgical simulation system that supports a COLLADA file format, which is a XML based 3D model data format and also proposes its extended file format to represent various information useful for the surgical simulation, i.e., several parameters for a spring model of the skin or the internal organs used as a haptic device parameters and several text-based data used as annotations...
This paper presents a novel method of contour reconstruction from dexel data solving the shape anomalies for the complex geometry in virtual sculpting. Grouping and traversing processes are developed to find connectivity between dexels along every two adjacent rays. After traveling through all the rays on one slice, sub-boundaries are connected into full boundaries which are desired contours. The...
Advances in Internet connections speeds and computer hardware means that web content has grown richer and more interactive for users. One such area is Web3D which has seen the emergence of ISO standard technologies such as VRML (Virtual Reality Modeling Language) and its XML-based (eXtensible Markup Language) successor X3D(eXtensible 3D). X3D, in particular, presents opportunities for further integration...
Building on the extensive research in Virtual Reality (VR), we are proposing a new dynamic prototype for modelling and simulating carbon emissions in a virtual village called VIRVIL. VIRVIL is a simulated settlement for the assessment of the impact of low and zero carbon technologies and measures in the built environment. The prototype will focus on the impact on the community as a whole, as well...
