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.Categories and Subject Descriptors (according to ACM CCS): I.3.3 [Computer Graphics]: Picture/Image Generation Viewing algorithms I.3.6 [Computer Graphics]: Methodology and Techniques I.3.7 [Computer Graphics]: Three-Dimensional Graphics and Realism
