Fast simultaneous visualization of 3D medical images and medical instruments is necessary for a surgical simulator. Because unconstrained motion of a medical instrument is more frequent than that of the patient, the visualization of medical instruments is performed in real time using surface rendering. However, volume rendering is usually used for realistic visualization of the 3D medical image...

3D space registration and visualization has become an imperative need in order to optimally reflect all complex cases of rapid urbanization of property rights and restrictions. Besides, current technological advances as well as the availability of sophisticated software packages (proprietary or open source) call for 3D modeling especially in the GIS domain. Within this context, GIS community’s ...

This thesis is split into two parts: one part dealing with the management of occlusion in 3D environments, the other with the visualization of causal relations. Both of these parts fall within the general framework of visualization—the graphical representation of data (abstract or concrete) with the purpose of amplifying cognition—but they do so in different ways. 3D occlusion management, on th...

Vegetation objects represent one main compositional element of digital models of our environment required by a growing number of simulation, analysis, and visualization applications. However, a detailed representation of vegetation in 3D spatial models is generally not feasible due to the lack of up-to-date, object-based, and area-wide tree surveys and computational limits in data acquisition, ...

ion: how does the design support information structuring and information hiding? Affordances: how does the design show the users what they can do with it? The rest of this paper is divided into four sections. Section 2 discusses the three cognitive aspects used to classify 3D information visualization designs. In Section 3, fifteen important designs are described and compared using the three co...

We present a set of interactive 3D visualizations, designed to explore oil/gas reservoir simulation post-processing models. With these visualizations we aim to provide reservoir engineers with better access to the data within their 3D models. We provide techniques for exploring existing oil well trajectories, and for planning future wells, to assist in decision making. Our approach focuses on d...

We introduce a framework for interactive visualization of global flow features in large unsteady 3D flow fields. It is based on selective visualization using dense precomputed integral lines (streamlines, path lines) linked together with all other data attributes. This way we are able to provide an uniform and interactive environment for custom feature specification and visualization of non-loc...

Understanding the results of a multi objective optimization process can be hard. Various visualization methods have been proposed previously, but the only consistently popular one is the 2D or 3D objective scatterplot, which cannot be extended to handle more than 3 objectives. Additionally, the visualization of high dimensional parameter spaces has traditionally been neglected. We propose a new...

In this paper the capabilities of a modern spatial 3D display are exploited for medical visualization tasks. The system gives multiple viewers the illusion of seeing virtual objects floating at fixed physical locations. The usage of this kind of display in conjunction with 3D visualization techniques helps disambiguating complex images, so it is proven to be a real advantage for immediate under...

This paper presents Triva, a three dimensional visualization prototype conceived to the analysis of monitoring data collected in distributed environments. The basic idea of this prototype is to apply information visualization techniques in the context of parallel processing in order to render 3D graphics that enable a better understanding of parallel applications and resources. This paper prese...
