However, the conventional ray\u2010tracing technique requires complicated computation for each pixel in the image and a long processing time. Advantage is taken of the similarity among neighboring pixels, and ray\u2010tracing is executed only to certain selected pixels while using interpolation to determine the value of other pixels. A pixel\u2010selected ray\u2010tracing algorithm is proposed. This paper presents first a description of the pixel\u2010selected ray\u2010tracing concept\/algorithm. Then methods of determining whether a pixel value should be calculated by ray\u2010tracing or by interpolation are discussed. Experiments were conducted to compare the proposed method with the standard ray\u2010tracing method. Experimental results indicated that the proposed method required only 20 to 63 percent of the computation time of the standard method, while rendering a comparable level of image quality.<\/jats:p>","DOI":"10.1002\/scj.4690181105","type":"journal-article","created":{"date-parts":[[2007,7,7]],"date-time":"2007-07-07T13:03:12Z","timestamp":1183813392000},"page":"41-49","source":"Crossref","is-referenced-by-count":0,"title":["Pixel\u2010selected ray\u2010tracing"],"prefix":"10.1002","volume":"18","author":[{"given":"Takaaki","family":"Akimoto","sequence":"first","affiliation":[]},{"given":"Kenji","family":"Mase","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2007,3,21]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1145\/358876.358882"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1145\/357323.357324"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/MCG.1984.6429331"},{"key":"e_1_2_1_5_2","article-title":"A High\u2010Speed Ray\u2010Tracing Algorithm using Extent Voxels","volume":"1180","author":"Akimoto","year":"1985","journal-title":"1985 I.E.C.E.
