The texture of feather is one of the most fascinating, complicated, and beautiful texture patterns in nature. In this paper, we propose a new and effective texture generation approach that uses the traits of iteration behavior to synthesize the textures of Galliformes feathers realistically. We also propose an interactive feather modeling approach which provides a close connection between the user's intuition and the resulting branching pattern. In texturing the feather structure, we use an object‐space mapping technique. Experimental results are presented to show the effectiveness of our method.
