Abstract

When 3D objects are rendered on a display using Computer Graphics technique, perspective projection that is based on a pinhole camera model is usually used. On the other hand, many of illustrations and artistic paintings are projections that are distorted and exaggerated partially affected by the human perception. Such projections are called Nonperspective projections, and it is studied as the model that seamlessly combines the projections from multiple viewpoints into one projection. However, there is no mechanism in the previous work that controls unnatural distortions in a projection by using the compositional arrangement of objects. Therefore, in this paper, we present a novel method that automatically controls a nonperspective projection avoiding the unnatural distortions as a whole by using a compositional arrangement of 3D scene objects. First, psychology experiments are conducted in order to clear the law between the tolerance of distortions in a nonperspective projection and a compositional arrangement of local linear perspectives. In addition, we present a method for editing a nonperspective projection while keeping distortions unnatural by using the results of the experiments as constraints on the edit of the nonperspective projection.
