A Level-of-Detail Technique for Urban Physics Calculations in Large Urban Environments
(The Eurographics Association, 2019)
In many applications, such as urban physics simulations or the study of the solar impact effects at different scales, complex 3D city models are required to evaluate physical values. In this paper we present a new technique ...
Procedural Location of Roads Using Desire Paths
(The Eurographics Association, 2019)
Procedural modelling of realistic environments that include elements derived from human activity can largely reduce production cost in animation, video-games and feature films. We address the problem of placing roads and ...
User-reconfigurable CAD Feature Recognition in 1- and 2-topologies with Reduction of Search Space via Geometry Filters
(The Eurographics Association, 2019)
In the context of Computer-Aided Design and Manufacturing, the problem of feature recognition plays a key role in the integration of systems. Until now, compromises have been reached by only using FACE-based geometric ...
Smooth Transitioning Between two Walking Metaphors for Virtual Reality Applications
(The Eurographics Association, 2019)
Virtual navigation should be as similar as possible to how we move in the real world, however the limitations of hardware and physical space make this a challenging problem. Tracking natural walk is only feasible when the ...
Prototype of an Automatic Registration System for the Remains of Archaeological Sites
(The Eurographics Association, 2019)
Data acquisition in archaeological excavations is a time consuming task developed on site that must be completed later with the information stored in the database. In this paper, we introduce the work in progress for the ...
A Voxel-based Deep Learning Approach for Point Cloud Semantic Segmentation
(The Eurographics Association, 2019)
Semantic segmentation has been a research topic in computer vision for decades. This task has become a crucial challenge nowadays due to emergence of new technologies such as autonomous driving. Nonetheless, most existing ...
A Virtual Reality Front-end for City Modeling
(The Eurographics Association, 2019)
Current tools for city modeling, including those supporting procedural techniques, have a steep learning curve and require substantial user input and/or skills to create realistic 3D models of cities. In this paper we ...
A Virtual Reality Front-End for Earthquake Simulation
(The Eurographics Association, 2019)
Virtual Reality has traditionally been used in Cultural Heritage for giving to the final user an immersive experience over recreated scenarios, which usually have been designed and focused on static environment recreation. ...
Multispectral Registration, Undistortion and Tree Detection for Precision Agriculture
(The Eurographics Association, 2019)
Multi-lens multispectral cameras allow us to record multispectral information for a whole area of terrain, even though we may only need the vegetation data. Based on the intensity of each multispectral image we can retrieve ...
Structure-preserving Style Transfer
(The Eurographics Association, 2019)
Transferring different artistic styles to images while preserving their content is a difficult image processing task. Since the seminal deep learning approach of Gatys et al. [GEB16], many recent works have proposed different ...
