Abstract in different language:	Shape characteristics play an important part in computer graphics. They help us to better understand various properties of geometrical objects. One of the most important shape characteristics is curvature. However, the curvature itself is not always enough and other characteristics have to be utilized. Those can be based on: angles between triangles, distances of points, topology of models, volume, area etc. Once the characteristics of the object are obtained, there are many ways how to use them. They can show important parts, such as: edges, sharp features, regions of interest etc. Other very common use cases are object matching and recognition. There are many different algorithms for shape characteristics with a different quality and performance. In the first part, we focus on curvature-based characteristics and related algorithms. We present a new solution for curvature estimation in the screen space. The second part is focused on other shape characteristics.
