There are various 3D visualization methods such as volume rendering and surface renderingS The volume rendering (VR) is a useful tool to visualize 3D medical images. However, a requirement of large computation amount makes it difficult for the VR to be used in real-time medical applications. In order to overcome the large computation amount of the VR, we have developed a progressive VR (PVR) me...

This paper presents a two-semester course covering basic VR concepts, VR interfaces, modelling techniques for VR applications, algorithms and programming languages for efficient design and implementation of VR applications. Details about an e-Course on Modelling and Programming VR applications are also presented according to the Open Distance Learning requirements.

BACKGROUND The use of virtual reality (VR) has gained increasing interest to acquire laparoscopic skills outside the operating theatre and thus increasing patients' safety. The aim of this study was to evaluate trainees' acceptance of VR for assessment and training during a skills course and at their institution. METHODS All 735 surgical trainees of the International Gastrointestinal Surgery ...

The loop-mediated isothermal amplification (LAMP) method was developed to distinguish between the varicella-zoster virus (VZV) vaccine (vOka) strain and wild-type strains. Two single nucleotide polymorphisms (SNPs) (nucleotide [nt] 105705 for VR-1 VZV LAMP and nt 106262 for VR-2 VZV LAMP) located in the open reading frame 62 gene were selected as LAMP targets. Amplified vOka DNA demonstrated a ...

background: liver cancer mortality is high in thailand but utility of related vital statistics is limited due to national vital registration (vr) data being under reported for specific causes of deaths. accurate methodologies and reliable supplementary data are needed to provide worthy national vital statistics. this study aimed to model liver cancer deaths based on verbal autopsy (va) study in...

To display special purpose 3D objects on Virtual Reality (VR) systems, when they can be analyzed intuitively and easily, it is possible for those 3D objects to be applied to cultural property research. It is sometimes difficult for users who are not familiar with VR to control objects displayed in VR according to their intention. Therefore, to control VR objects for such users, operations of VR...

Compared to previous years, virtual reality has recently developed at an unprecedented speed. Philosophers have also noted the importance and philosophical dimension of Virtual Worlds, as well their potential for arts, VR plays roles similar physical may be freely created. For artists been interested in a medium which is possible use creative process and/or exhibiting purposes. Several dimensio...
