It presents algorithms for intermediate quality shading i.e. the quality of shading is better than Gouraud shading and nearly comparable to the quality of bi-quadratic Phong shading, at the same time, algorithms are very fast as compared to bi-quadratic Phong shading. Three algorithms are discussed. The first algorithm uses hybrid shading in which bi-quadratic interpolation of intensity is performed on the edges of a triangle and linear interpolation of intensity is performed on the scan line. Hybrid shading, in which bi-quadratic interpolation of normals is performed on the edges and linear interpolation of intensity is performed on the scan line, has been proposed in the second algorithm. In the third algorithm, bi-cubic interpolation of intensity is performed on the edges and linear interpolation of intensity is performed on the scan line. The paper also presents an incremental method for fast calculation of area coordinates and shape functions enhancing the speed of the algorithms. <\/jats:p>","DOI":"10.1142\/s0219467805002002","type":"journal-article","created":{"date-parts":[[2005,11,22]],"date-time":"2005-11-22T08:48:37Z","timestamp":1132649317000},"page":"789-810","source":"Crossref","is-referenced-by-count":3,"title":["FAST HYBRID SHADING: AN APPLICATION OF FINITE ELEMENT METHODS IN 3D RENDERING"],"prefix":"10.1142","volume":"05","author":[{"given":"CHANDAN","family":"SINGH","sequence":"first","affiliation":[{"name":"Department of Computer Science, Punjabi University, Patiala, Punjab 147002, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"EKTA","family":"WALIA","sequence":"additional","affiliation":[{"name":"National Institute of Technical Teachers Training and Research, Sector 26, Chandigarh, Union Territory 160019, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1145\/263834.263849"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1145\/360825.360839"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1007\/s003710100111"},{"key":"rf4","first-page":"43","volume":"3","author":"Grit T.","journal-title":"Journal of Graphics Tools"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1080\/10867651.1999.10487501"},{"key":"rf6","doi-asserted-by":"publisher","DOI":"10.1145\/15886.15897"},{"key":"rf7","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-8659.1989.tb00513.x"},{"key":"rf8","first-page":"825","volume":"9","author":"Mohamed A.
