The area had remained allied with the nationalist communist forces from the beginning of the French war in 1946 to the fall of Saigon in 1975: an exception in a country often torn region by region between control by American forces and control by the Viet Cong.

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.
