| dc.description.abstract | Virtual environments and user interfaces in general can be improved by using the concept of Perceptual Realism, e.g. by means of non-photorealistic rendering techniques. The approach presented here follows a different path by reducing perceived geometric distortions, which typically occur for spherical objects while rendering scenes with a large angle of view. Learning from painting, we adopt the Renaissance painters principle of using multiperspective views and propose a perspective correction technique to overcome the mentioned problem. With it, three-dimensional transformations directly modify the geometry of particular objects within a scene to countervail their distortion during the rendering process. The approach results in an improved perceptual realism of the rendered images. | en_US |
