Abstract: Non-photorealistic rendering has been attracting attention in the field of computer graphics. A common approach to artistic rendering is using a shape model which utilizes mesh data. In recent years, the use of point clouds as shape models has increased due to the rapid development of 3D-scanners used to create them. Correspondingly, there has been an increase in the research on point clouds. We propose a stipple rendering method as a type of artistic rendering for point clouds, based on a hybrid image/object space. First, we eliminate hidden points based on an image space. Next, we apply a novel shading method to the visible points based on an image space. Lastly, we apply the above two results to the input point cloud. We implement the proposed method using a graphics processing unit to accomplish the interactive rendering. The experimental results show that we can achieve shading and shadowing interactively.
