The focus of the project is the investigation and evaluation of methods for creating a direct linkage between procedural generation methods for complex objects (landscapes, urban structures) and non-photorealistic rendering (NPR) methods, which automatically creates abstract renditions of these objects in, e.g. a painterly look. Traditionally, for producing such abstract renditions objects are first rendered photorealistically and then converted into abstract, non-photorealistic representations in a second step. The combination of procedural generation and abstract rendering methods allows us to achieve methods, which are able to obtain required additional information directly from a scene without being dependent on a photorealistic intermediate image. By creating a direct link, information can be used that improves not only the quality of the resulting non-photorealistic representations, but includes also object-specific or context-related information (spatial depth, object weight and type). Using three model scenarios that focus on complex city models, urban spaces and nature, this combination is exemplarily investigated. Different abstraction algorithms will be implemented and different procedural generation methods will be tested for their suitability for a direct representation. For example, it must be ensured that the geometrical abstraction has an adequate correspondence in the procedural generation.

该项目的重点是研究和评估用于在复杂对象（景观，城市结构）和非遗嘱现实主义渲染（NPR）方法之间建立过程生成方法之间直接链接的方法，这些方法自动创建了这些对象的抽象复发。绘画的外观。传统上，为了产生这种抽象的演绎对象，首先是通过光真呈现的，然后在第二步中转换为抽象的非遗迹表示。程序生成和抽象渲染方法的组合使我们能够实现方法，这些方法能够直接从场景中获取所需的其他信息，而无需依赖于逼真的中间图像。通过创建直接链接，可以使用信息，不仅可以改善所得非遗嘱代表的质量，还包括特定于对象或上下文相关的信息（空间深度，对象重量和类型）。使用三种型号方案，专注于复杂的城市模型，城市空间和自然，这种组合得到了典范的研究。将实施不同的抽象算法，并将测试不同的程序生成方法的直接表示。例如，必须确保几何抽象在程序生成中具有足够的对应关系。
