Abstract :
Silhouettes play a critical role in non-photorealistic rendering. The effect of the NPR greatly depends on the silhouette performance. And it is also a key technology for real-time NPR applications. This paper introduces the most popular and latest techniques in silhouette detection. We classify and analyze them, and discuss them with the problem of visibility determination. After analyze the advantage and disadvantage of them, the working context of them is also concluded.
