comers. Much relevant knowledge is only available at data providers and software vendors level which make it difficult to get an independent advice. On the other hand, the demand is not always clear which makes it hard for data providers and software vendors to offer demand-oriented products and services. Despite the slow progress of 3D in practice, it is clear that 3D applications are importan...

The aim of this study was to assess how certain tools in 3D volume visualization software aid physical scientists in their visual analysis of 3D data sets. The KeckCaves collaboration has lead to continuing development of a 3D volume visualization software package called Visualizer, which is built on the Virtual Reality User Interface (VRUI) Toolkit designed by Oliver Kreylos. Visualizer can be...

Advances in technology are making it possible to run three-dimensional (3D) graphics applications on embedded and handheld devices. In this article, we propose a hardware/software co-design environment for 3D graphics application development that includes the 3D graphics software, OpenGL ES application programming interface (API), device driver, and 3D graphics hardware simulators. We developed...

BACKGROUND 3D transesophageal echocardiography (TEE) is superior to 2D TEE in quantitative anatomic evaluation of the mitral valve (MV) but it shows limitations regarding automatic quantification. Here, we tested the inter-/intra-observer reproducibility of a novel full-automated software in the evaluation of MV anatomy compared to manual 3D assessment. METHODS Thirty-six out of 61 screened p...

RMR, Rock Mass Rating, is one of the famous rock classifications. However, RMR was proposed empirically and absolutely depends on the experience of engineer. Therefore, engineering verification is needed for RMR system itself. In this study, the factor analysis and the multiple regressions were performed in order to evaluate the validity of rating factor of RMR. Also numerical analysis was carr...

RNA structures are hierarchically organized. The secondary structure is articulated around sophisticated local three-dimensional (3D) motifs shaping the full 3D architecture of the molecule. Recent contributions have identified and organized recurrent local 3D motifs, but applications of this knowledge for predictive purposes is still in its infancy. We recently developed a computational framew...

Conventionally, a 2D image can be captured by a camera, composed and painted by a 2-button mechanical mouse (a digital brush) with a digital palette. A 3D object can be modeled by 3D (translate, rotate, scale, transform) software or formulated by equation-based method. Be it 2D images or 3D objects, the result can be displayed on a 2D image on screen or print it on a given surface. The color an...

Generation of 3D city models has been evolving to be one of the most relevant and active research topics as many application areas require them. Planning of Telecommunications, Urban development, Managing disasters, Prevention of Hazards, City design, developing TV games, etc., are some of the application areas where 3D city models are precisely and accurately needed. Several concepts from Geo-...

The 'omics' revolution is causing a flurry of data that all needs to be annotated for it to become useful. Sequences of proteins of unknown function can be annotated with a putative function by comparing them with proteins of known function. This form of annotation is typically performed with BLAST or similar software. Structural genomics is nowadays also bringing us three dimensional structure...
