Challenge<\/h4>\n

Real-time 3D exploration of digital elevation and urban models is one of the most important components in a number of practical applications. Massive high accuracy datasets are routinely generated through specialized modeling solutions as well as a variety of capture settings, from satellites to planes and drones. The resulting models need specialized techniques to be effectively explored and rendered.<\/p>\n

Overview<\/h4>\n

Over the past decades, we have designed and developed a suite of multi-resolution out-of-core techniques for rapid high-quality distribution and visualization of textured digital terrain models and high resolution urban environments. Our solutions include advanced mesh refinement for creating seamless variable-rate representations suitable for GPU-accelerated rendering, aggressive compression techniques capable to support maximum-error constraints and GPU-friendly approximated far-field representations of textured urban data. Many of these solutions have been integrated in an open-source code (rat-man), that has been employed in a variety of settings, including regional and national-scale distributed geoviewing systems. Our adaptive solutions have also been used for simulation applications in the space domain.<\/p>\n
