A cartoon-style rendering for physical dynamic hair animation

Hair rendering is one of the major research topics in computer graphics. A lot of papers on hair modeling have focused on photo-realistic rendering. This paper proposes a stylized cartoon hair rendering flow diagram including animated hair strand creation, stroke path generation, brush stroke line simulation, and expressive hair rendering. A reordering mechanism addresses depth and stroke line rendering for a suitable performance and temporal coherence. The proposed method creates a delicate expression similar to an artist's drawing. To validate real-time performance, all stroke effects are rendered with different shaders on a graphics processing unit. The method is flexible enough to allow users to select shader effects and control the parameters of each activated shader to create esthetically pleasing results. Finally, the proposed method produces excellent experimental results. These results are compared to the results of previous studies.
