The Iron Triangle (film) The Iron Triangle (film) The Iron Triangle is a 1989 film about the Vietnam War shot in Sri Lanka and directed by Eric Weston. The story is based on the diary of an unknown Viet Cong Soldier. This unique fact gives the movie a different perspective than many of the other movies about the Vietnam war and makes black and white distinctions about who were the "good guys" and "bad guys" a little more complicated. The film stars Beau Bridges, Haing S. Ngor, Liem Whatley, Johnny Hallyday, Jim Ishida, and Ping Wu. Each character helps bring to life the struggle
Bézier triangle Bézier triangle A Bézier triangle is a special type of Bézier surface, which is created by (linear, quadratic, cubic or higher degree) interpolation of control points. A general "n"th-order Bézier triangle has ("n" + 1)("n" + 2)/2 control points "a" "β" "γ" where "i", "j", "k" are nonnegative integers such that "i" + "j" + "k" = "n" . The surface is then defined as for all nonnegative real numbers "s" + "t" + "u" = 1. With linear order (formula_2), the resulting Bézier triangle is actually a regular flat triangle, with the triangle vertices equaling the three control points.
