Modeling natural phenomena is a problem that has been studied for a long time in Computer Graphics. A problem that currently arises is how to render and animate realistically natural phenomena in real-time. This paper presents a technique to model underbrush with fast and realistic animation. Pre-computations and a simplified physically based model were(More)
Recent advances in Agricultural Engineering include image processing, robotics and geographic information systems (GIS). Some tasks are still accomplished manually, like drawing plantation lines that optimize productivity. Herewith we present an algorithm to find the optimal plantation lines in linear time. The algorithm is based upon classical results of(More)
Region filling is one of the most important and fundamental operations in computer graphics and image processing. Many filling algorithms and their implementations are based on the Euclidean geometry, which are then translated into computational models moving carelessly from the continuous to the finite discrete space of the computer. The consequences of(More)
