$triregiontype

The $triregiontype is defining the triangular shape range's arrange method. The format is

$triregiontype
@type  @periodnumber @period_spacing($\mu m$ )
...
...   repeat the number of triangular region number $triregionnumber$

@type: 
1 : triangular , period along x if the periodnumber >1 
11 : triangular , period along y if the periodnumber >1 
2 : circular shape, period along x if the periodnumber >1 
21 :   circular shape, period along y if the periodnumber >1 
3 : elliptic shape, period along x if the periodnumber >1 
31 :   elliptic shape, period along y if the periodnumber >1 
4 : elliptic shape, period along x if the periodnumber >1 
41 :   elliptic shape, period along y if the periodnumber >1 

Example

$triregionnumber
2

This means that there are two triangular regions. This command must be set after the command $ranges. The "triregionnumber" must be smaller than the "range number".

This command needs to be set before the command before the commands $triregiontype, $triranges,

For example:

$triregionnumber
2

$triregiontype
1 1 2.0
4 5 3.0

$triranges
@x1 @y1 @x2 @y2 @x3 @y3
@x1 @y1 @x2 @y2 @x3 @y3

x1,y1,x2,y2,x3,y3 are 3 vertex points of triangular
