Exhibit Hall OpenGrand Ballroom Salons 3-6 Tuesday 1:00 pm- 7:00 pm Consider Stereoscopy From Outset: The Adjustments in 3D Scenes for Stereoscopic PresentationShih-Chueh Kao (University of Leeds, United Kingdom) The Film Studios' drive to release stereoscopic films is causing a fundamental change in filmmaking that is ripping through the production process. Filmmakers increasingly would like to embed stereoscopy into the production from the outset. The key factors of successful stereoscopic illusion are no longer only an afterthought process in post‐production but are moving further upstream in stereographer’s depth script and CG designers’ comprehensive contemplation. Modeling, texturing, lighting, objects’ position and cameras’ layout are all techniques and factors in 3D scenes that should be taken into account by CG designers. In addition to cinema technical challenges, “ghosting” and “buzzing” would be the foremost problems in viewer experience. In a stereoscopic illusion created by two images rendered from two cameras, ghosting and buzzing may occur if two images weren’t match perfectly. These minor imperfections, although leading only to tiny differences, can confuse viewers’ brains and cause ghosting or buzzing especially when viewing on a large screen. CG designers have to minimize the difference between two cameras to reduce these perceptual artifacts. Modeling, texturing, lighting, objects’ position and cameras’ layout in 3D scenes could be adjusted for greater matched images. For example, different mapping methods would cause different results between left and right views. In my testing, two mapping methods (bump map and displacement map) are compared, when drawing near the object to the cameras, bump map may result in normal quality of the object in one viewport, but when seen through the other viewport, noticeable rough edges appear, and this would cause buzzing error in the subsequent stereoscopic images. Displacement map would be the better choice because it results in parallel quality images in both cameras. This paper will discuss techniques and factors that related to correctness of stereoscopic presentation, analyze the results from different testing and provide the references and suggestions for CG designers who work for stereoscopic effect.
