Real-Time Rendering of Vegetation and Trees in Urban Environments
نویسندگان
چکیده
In our System we have employed a number of different vegetation visualization methods, including point-based rendering, impostors and billboard clouds. Based on these experiences we have designed an urban rendering system that can deal with thousands of trees, facilitating real-time visualization of urban recreation areas such as parks and green-belts. Based on the application different techniques are used in order to provide optimal performance in each situation. Thus it is possible to render single trees with adequate detail for walk-throughs as well as whole woods for fly-over applications.
