چکیده

Forest resource management systems and forest landscape visualization applications often need usersteered interactive displays of a forest landscape representing the underlying forest inventory database. We present an approach for dynamically modeling and real-time rendering of a real forest. A parameterized procedural tree model is given with a hybrid representation method and a specific level of detail algorithm for ensuring real-time frame rates. Forest inventory data, together with predefined tree parameter templates, drive the modeling engine to generate visual realistic 3-D tree models on the fly. We have evaluated our approach by applying it in a GIS-based forest resource management system to construct a virtual forest with immersive capability for navigation, query, and analysis.

Ubiquitous Interactive Visualization of 3-D Mantle Convection through Web Applications Using Java

We have designed a new system for real-time interactive visualization of results taken directly from large-scale simulations of 3-D mantle convection and other large-scale simulations. This approach allows for intense visualization sessions for a couple of hours as opposed to storing massive amounts of data in a storage system. Our data sets consist of 3-D data for volume rendering with sets ra...

Realistic and Interactive Visualization of High-Density Plant Ecosystems

Modeling and visualization of natural and realistic outdoor ecosystems like forests or meadows remains a highly challenging task in computer graphics. Convincing and non-artificial scenes require many thousands to millions of plants, each modeled with a high degree of geometric, shading, and lighting detail. At the same time many applications demand interactive rendering at high fidelity. In th...
