Variations in 2D and 3D Models by a New Family of Subdivision Schemes and Algorithms for its Analysis

Algorithm 5

Bell-shaped mask of the proposed schemes.

(1)	input: The mask of the family of proposed schemes whose mask symbol is defined in (11),
(2)	set:
(3)	for to do
(4)	calculate: an interval, say , for by solving
(5)	end for
(6)	calculate: intersection, say , of intervals
(7)	for to do
(8)	calculate: an interval, say , for by solving
(9)	end for
(10)	calculate: intersection, say , of intervals
(11)	calculate: intersection, say , of 2 intervals and
(12)	return, ,
(13)	output: the proposed -point scheme has a bell-shaped mask for
