For complex scenes, calculation of this model is very time\u2010intensive, due largely to the determination of a geometric factor, defined with a double area integral, and named form factor. This paper presents a new expression of the form factor, which can be reformulated, in a computationally more efficient manner, as a simple line integral for planar polygonal convex surfaces that are perfectly diffuse.<\/jats:p>Recently, parallel computers have been used to decrease calculation time. Previous work is focused mainly on distributed implementations of a method, the progressive refinement method, widely used for complex environments. The T.Node is a completely reconfigurable MIMD machine, based on the transputer chip. In this paper, we compare a parallel implementation of the progressive refinement method with a direct method which takes into account the memory capabilities of this kind of machine.<\/jats:p>","DOI":"10.1111\/1467-8659.1230421","type":"journal-article","created":{"date-parts":[[2003,3,11]],"date-time":"2003-03-11T11:31:52Z","timestamp":1047382312000},"page":"421-432","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Form Factor Calculation: a New Expression with Implementations on a Parallel T.Node Computer"],"prefix":"10.1111","volume":"12","author":[{"given":"Sylvain","family":"Michelin","sequence":"first","affiliation":[]},{"given":"Gualtiero","family":"Maffeis","sequence":"additional","affiliation":[]},{"given":"Didier","family":"Arqu\u00e8s","sequence":"additional","affiliation":[]},{"given":"Jean Claude","family":"Grossetie","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2008,10,9]]},"container-title":["Computer Graphics Forum"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2F1467-8659.1230421","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/1467-8659.1230421","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,25]],"date-time":"2023-10-25T00:39:21Z","timestamp":1698194361000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/1467-8659.1230421"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1993,8]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[1993,8]]}},"alternative-id":["10.1111\/1467-8659.1230421"],"URL":"https:\/\/doi.org\/10.1111\/1467-8659.1230421","archive":["Portico"],"relation":{},"ISSN":["0167-7055","1467-8659"],"issn-type":[{"value":"0167-7055","type":"print"},{"value":"1467-8659","type":"electronic"}],"subject":[],"published":{"date-parts":[[1993,8]]},"assertion":[{"value":"2008-10-09","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
