Abstract :
This paper presents a sketch rendering method based on GPU, which can simulate the style of pencil drawing. The method is divided into several steps. First, by use of rendering to texture technology and Sobel edge detection method to get the silhouette of the texture image. Second, render the model through dynamic UV coordinate mapping from a stroke texture group[1], and then blend the silhouette image and textured model. Finally, through adding Multi-Lighting method to improve the performance effect.
