Creating abstract digital paintings with painting camera technique

摘要

We present a simple and intuitive rendering technique to create abstract paintings. This technique allows the users to render a given animated scene with multiple cameras, using a method inspired by concepts used by cubist and futurist abstract painters. In our method, the number of cameras is unlimited and the camera parameters are continuous functions. We define the camera parameters as parametric functions that are described by images, which we call camera-control-images. The spatial distribution color in these camera-control-images determines the camera parameters such as position and orientation. For the creation of abstract paintings, we have developed two artistic techniques. In the first technique, artists incrementally paint a complicated camera-control-image for a given 3D scene. The second technique is the opposite of the first. In this technique, for a given camera-control-image artists incrementally built a 3D scene to create an interesting abstract painting. The second technique is helpful when using existing images such as photographs and paintings.
