Terrain Analysis

One main source of information were cartographic maps of the “Esteros del Iberá” developed by the Military Geographic Institute (IGM, Instituto Geográfico Militar). Nineteen maps in the scale 1:100000 were required to cover the study area. The main information retrieved from the maps were the Level Curves (LC). We decided to use the LC in order to define the limits of the watershed by using a G...

Procedural Terrain

We produce procedurally generated terrain consisting of geometry and textures. Geometry is created using the GPU at run-time. The textures are precomputed using the CPU and saved to disk for later access. A shader applies textures without the use of UVs to the geometry to create complex and interesting environments that are interactive in real-time.

Terrain-Based Genetic Algorithm (TBGA): Modeling Parameter Space as Terrain

The Terrain-Based Genetic Algorithm (TBGA) is a self-tuning version of the traditional Cellular Genetic Algorithm (CGA). In a TBGA, various combinations of parameter values appear in different physical locations of the population, forming a sort of terrain in which individual solutions evolve. We compare the performance of the TBGA against that of the CGA on a known suite of problems. Our resul...

Learning a Terrain Model for Autonomous Navigation in Rough Terrain

Current approaches to local rough-terrain navigation are limited by their ability to build a terrain model from sensor data. Available sensors make very indirect measurements of quantities of interest such as the supporting ground surface and the location of obstacles. This is especially true in domains where vegetation may hide the ground surface or partially obscure obstacles. This thesis pre...
