摘要:

植物的放置在虚拟场景的真实感中起着核心作用。我们介绍了程序放置模型(PPM)的城市布局中的植被。PPM对城市几何形状具有环境敏感性,可以根据城市布局中的结构和功能区确定合理的工厂位置。可通过定义参数直接使用生产和生产方法,也可从卫星图像和土地登记数据中了解生产和生产方法。再加上生成建筑物和树木的方法,这使我们能够用复杂的3D植被填充城市景观。我们的框架的有效性,通过大规模的城市场景和特写镜头的单独生长的树模型的例子,我们还验证了它的感知用户研究。

英文摘要:

The placement of vegetation plays a central role in the realism of virtual scenes. We introduce procedural placement models (PPMs) for vegetation in urban layouts. PPMs are environmentally sensitive to city geometry and allow identifying plausible plant positions based on structural and functional zones in an urban layout. PPMs can either be directly used by defining their parameters or can be learned from satellite images and land register data. Together with approaches for generating buildings and trees, this allows us to populate urban landscapes with complex 3D vegetation. The effectiveness of our framework is shown through examples of large-scale city scenes and close-ups of individually grown tree models; we also validate it by a perceptual user study.
