The feature-line extraction of a 3D model is a key step in the model-based Non-Photorealistic Rendering. In this paper, we introduce a new algorithm that is based on a sharpening filter to extract the feature-lines of 3D models. Experiments of feature-line rendering where our sharpening filter is introduced as a pre-calculation step are shown to compare with the existing algorithms ([1][2][3]). From these experiments it can be found that our rendering results reserve more feature details and contain less noise. Furthermore, in our algorithm, the computation time of rendering is also reduced.
