derived from Paul Stansifer's POV-Ray source files (see below), by me, 84user, using w:en:POV-Ray, and w:en:IrfanView. 84user's contribution (inside POV-Ray files: adjusting coordinates, changing light source and other parameters) is public domain and source files used are described at User:84user/Size comparison. Physical information is based on the Wikipedia articles and elsewhere (see POVRay source files) about the respective lengths. Paul Stansifer's contributions to this image (POV-Ray code) are available under the GPL, v. 2, and other licenses. See User:Paul Stansifer/Size comparison for more details and the other licenses. |
