This paper presents a simple approach for adding more details to non-photorealistic image without increasing the complexity of the model. Bump mapping technique is introduced to create the details that can vary automatically with the change of light and view direction, but this technique originally aims to make a rendered surface look more realistic, so we present an algorithm to stylize it the same to achieve overall stylistic effect. We also present a novel approach for drawing multiple lines in GPU, and all the algorithms in this paper are based on GPU.
