Coherent Stylized Lines for Mesh Surfaces by Contour Triangles

摘要

This paper presents a method to render smooth stylized contours of 3D meshes with temporal coherence. Contour triangles that contain countour curves perform two functions: they ensure that smooth contour curves are coherent and reconstructed faithfully during the motion of the viewpoint and they help to establish the corresponding relationship of contours which can propagate parameters on contours between frames against sliding effects. Our method can also deal with zig-zags and short segments for coarse meshes and nonuniform sampling meshes in a wide range of styles very well.
