Abstract: We present a rendering method that generates 3D Chinese ink painting effect based on point cloud tree models. First, the tree model is divided into three parts: trunk, branches and leaves. Then, each part is rendered according to different characteristics. For the trunk, a hybrid texture mapping method is proposed to generate the ink painting effect. The branches are filled directly by using the average color of the trunk texture. For the leaves, a series of stylized steps are proposed which include model simplification, stroke facets construction, painting direction determination, ink color determination, brush model construction, rendering and ink diffusion. Experimental results demonstrate that the proposed method here is efficient and effective.
