Visualizing massive computation fluid dynamic outputs in game engines using voxelization and dynamic loading

Computation Fluid Dynamics (CFD) simulations are used in a diverse set of fields such as aerodynamics, automotive, biomedical engineering and wind impact. With the advancements in technology the scale of these simulations has increased significantly. This has resulted in \textit{massive} CFD simulations --- simulations that do not fully fit...

Weathering and debris simulation on high-resolution voxel scenes

Voxels are cells on a 3D regular grid. Voxel-based scenes have many applications, including frequent use in simulations or games. Over the years, the field of high-resolution voxel scenes has progressed significantly, allowing for compressing and real-time editing of high-resolution scenes. This possibility of editing high-resolution scenes led...

A voxel-based methodology to detect (clustered) outliers in aerial lidar point clouds

To obtain 3D information of the Earth’s surface, airborne LiDAR technology<br/>is used to quickly capture high-precision measurements of the terrain.<br/>Unfortunately, laser scanning techniques are prone to producing outliers<br/>and noise (i.e. wrong measurements). Therefore, a pre-process of the point<br/>cloud is required to detect and...

Detection of doors in a voxel model, derived from a point cloud and its scanner trajectory, to improve the segmentation of the walkable space

Generation of indoor networks for navigation will normally be done out of standard floor plans that are only 2D and is more often manual than automatic. These floor plans are drawn at a specific time and do not correspond to the reality, moreover some of those buildings were built already differently than designed. Then in due course the...

3D Intersection operations for voxel data represented as surfaces in GIS

This thesis focusses on the intersection 3D Boolean set operation on voxel data represented as surfaces, with other 3D surface based vector data, in GIS. The Application of this research makes the linkage with geohydrology possible: based on the vectorised GeoTOP (TNO) data the water infiltration and storage capacity of specific locations can be...

Evaluating voxel enabled scalable intersection of large point clouds

Laser scanning has become a well established surveying solution for obtaining 3D geo-spatial information on objects and environment. Nowadays scanners acquire up to millions of points per second which makes point cloud huge. Laser scanning is widely applied from airborne, carborne and stable platforms, resulting in point clouds obtained at...

3D visualization of extra large data arrays by means of scientificVR® visualizer

Visualization of data is nowadays an indispensable part of scientific research and effect analysis practically in any field of natural sciences. Graphic presentation of the results in the form of color lay-outs or functional dependence diagrams makes it considerably easier to perceive new information and contributes to a more sophisticated and...
