3D visualization techniques enable an intuitive mediation of complex, space related facts. Civic participation in community landscape planning or visual simulations of landscapes could benefit from emerging computer graphics technologies. However, interactive visualization tools matching the special needs of landscape planning only exist in their beginnings. In 2000, the Centre for Agricultural...

The Virtual Reality Modeling Language (VRML) was created to put interconnected 3D worlds onto every desktop. The 3D VRML format has the potential for 3D fax and TeleManufacture. An architecture and methodology of using VRML format to integrate a 3D model and Solid Freeform Fabrication system are described in this paper. The prototype software discussed in this paper demonstrates the use of VRML...

We discuss 3d interaction techniques for the quantitative analysis of spatial relations in medical visualizations. As an example, we describe the design and implementation of 3d distance measurement tools. The visualization of measurement tools as recognizable 3d objects and a 3d interaction, which is both intuitive and precise, determines the usability of such facilities. Moreover, we explain ...

BACKGROUND Three-dimensional (3D) printing is relatively a new technology with clinical applications, which enable us to create rapid accurate prototype of the selected anatomic region, making it possible to plan complex surgery and pre-bend hardware for individual surgical cases. This study aimed to express our experience with the use of medical rapid prototype (MRP) of the maxillofacial regio...

Osseointegrated titanium implants to the cranial skeleton for retention of facial prostheses have proven to be a reliable replacement for adhesive systems. However, improper placement of the implants can jeopardize prosthetic outcomes, and long-term success of an implant-retained prosthesis. Three-dimensional (3D) computer imaging, virtual planning, and 3D printing have become accepted componen...

Dental rehabilitation treatment planning includes the qualitative evaluation of all available data (eg. Panoramic x-rays, periapical x-rays, models of dental arches, intra-oral photographs, periodontal and dental measurements, registrations of occlusal relationships etc.) and choice of the appropriate strategy. For this planning to be effective both accurate 3D geometrical information and prope...

A post-hoc cognitive strategies visualization tool for operators in command and control environments, TRACS (Tracking Resource Allocation Cognitive Strategies) captures the critical steps performed in solving a resource allocation problem like those typically encountered in mission planning and replanning. TRACS presents a human operator’s cognitive strategies in a twodimensional space, using a...

Immersive environments are just beginning to be used to support mission operations at the Jet Propulsion Laboratory. This technology contributed to the Mars Pathfinder Mission in planning sorties for the Sojourner rover. Utilizing stereo imagery from the Imager for Mars Pathfinder (IMP) camera enabled the operator to visualize the terrain from the lander's point of view in 3D to assist in plott...

Introduction: Since commissioning beam data are treated as a reference and ultimately used by treatment planning systems, it is vitally important that the collected data are of the highest quality to avoid dosimetric and patient treatment errors that may subsequently lead to a poor radiation outcome. Beam data commissioning should be performed with appropriate knowledge and pr...

BACKGROUND To compare 3 Dimensional Conformal radiotherapy (3D-CRT) with Intensity Modulated Radiotherapy (IMRT) with Volumetric-Modulated Arc Therapy (VMAT) for bladder cancer. METHODS Radiotherapy plans for 15 patients with T2-T4N0M0 bladder cancer were prospectively developed for 3-DCRT, IMRT and VMAT using Varian Eclipse planning system. The same radiation therapist carried out all planni...
