In this article, we introduce a novel occlusion culling method working on the server side to provide real-time navigation on web-based systems. Nowadays, virtual navigation in urban environments is a rising trend in several contexts such as tourism, GPS navigation systems, and video games. A city environment is usually associated ...

Several geospatial problems like urban subsurface analysis involve data from multiple domains and nature. For instance, an urban infrastructure analysis must take into account not only the urban elements but their geological environment. This requires the definition of hybrid schemes and algorithms that keep the dimensionality and domain of the ...

Real-time visualization in web-based system remains challenging due to the amount of information associated to a 3D urban models. However, these 3D models are not able to provide advanced management of urban infrastructures, such as underground facilities. Nowadays, 3D GIS is considered the appropriate tool to provide accurate analysis and ...

The use of advanced software tools for groundwater management is essential to carry out the management of these underground infrastructure. Tools capable of accomplishing these processes are the so-called 3D GIS. However, these systems are not widely implemented, mainly because of their complexity. In this paper we present the data ...

The Path Planning problem is a common topic for Robotics and Computational Geometry. Many important results have been found to this classic problem, some of them based on plane or space tessellation. The new approach we propose in this paper computes a partition of the plane called the Polar Diagram, ...

The new approach we propose in this paper is a plane partition with similar features to those of the Voronoi Diagram, but the Euclidean minimum distance criterion is replaced for the minimal angle criterion. The result is a new tessellation of the plane in regions called Polar Diagram, in which ...

In computer graphics, collision detection is considered a key problem with important applications in related areas. Several solutions have been proposed, but independently of the chosen strategy, different stages of the solution are considered. It is not only relevant to apply a good static collision test, but reducing the pairs ...
