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 ...

In this paper we address the problem of fast inclusion tests and distance calculation in very large models, an important issue in the context of environments involving haptic interaction or collision detection. Unfortunately, existing haptic rendering or collision detection toolkits cannot handle polygonal models obtained from 3D digitized point clouds ...

Formal models can be useful in computer graphics as a conceptual framework supporting representation systems. This allows to formally derive properties and algorithms and proof their correctness and validity. This paper describes a formal model based on a geometric algebra. This algebra has been used to obtain specific representation systems ...

In this paper we present a robust and accurate method for evaluating regularized Boolean operations on triangulated solids. It allows the exact evaluation of the regularized union, intersection, difference and symmetric difference simultaneously. Moreover, this approach is simpler than other methods, including those that provide an approximate evaluation or only ...

Erosion in agricultural areas is accentuated by the effects of meteorological factors, tillage practices and the slope of the land. This latter effect leads to surface runoff which in turn causes the soil erosion. To carry out erosion models is necessary to use spatial data, like DEM, slopes models or ...

This work describes the EL-REP, a new 2D decomposition scheme with interesting properties and applications. The EL-REP can be computed for one or more simple polygons of any kind: convex or nonconvex, with or without holes and even with several shells. A method for constructing this decomposition is described in ...

This paper presents a scheme for decomposing polyhedra called multi-LREP. The scheme is based on the L-REP decomposition, which classifies the triangular faces of a polyhedron into a set of layered tetrahedra. In the multi-LREP these layered tetrahedra are grouped into regions of a space subdivision. The paper also describes ...

In this paper, a new algorithm for the intersection between a segment and a triangle in 3D is presented. This algorithm is suitable for interference tests between moving polyhedral solids, as is shown in the times study. In this situation it is necessary to determine whether the interference between triangles ...

The point-in-polygon or containment test is fundamental in computational geometry and is applied intensively in geographical information systems. When this test is repeated several times with the same polygon a data structure is necessary in order to reduce the linear time needed to obtain an inclusion result. In the literature ...
